    Input box to sum and display sum as msgbox

    Hello I am struggling to make this assignment happen:Create a macro procedure that asks for three integers (one at a time) and displays their sum in a message box.
    Insert a module into the project, then insert a macro procedure named AddThreeNumbers. Code this procedure so that when it is executed, it will ask for three integers (one at a time), store them into three variables respectively, computes their sum, and display “The sum of [1st num], [2nd Num], and [3rd Num] is [the sum of the three numbers].” where each square bracket should be replaced by the numbers that the user put in. That is, if the user put in 10, 20, and 30 into the three boxes, it should display “The sum of 10, 20, and 30 is 60.” Make sure you declare and use appropriate variables.
    1. The message box should have the title, “My Own Adder”.
    2. Insert an ActiveX Command button displaying a picture of your choice, with the caption, “I Add Three Integers.”
    3. Link the AddThreeNumbers procedure to the button so that when the button is clicked, the procedure is executed.
    4. Save and submit the workbook.
    I currently have this code but my input boxes are not being saved as a variable.

    Now I am getting an error message in my msgbox code when I add the Sum function. Addtionally, I still get the words "myValue..." in the message box not the numbers entered into the inputbox.

    Re: Input box to sum and display sum as msgbox

    This reads a lot like a homework or learning task.. so I will help you along the way but wont give the solution.

    Remember your basic math, it still applies in VBA...
    & will not sum anything & will just combine 2 strings into 1.

    you will need to make an actual calculation to get the sum and then show that as a result in the messagebox
    the 3 variables that store the results of the inputboxes is a good start..

    Re: Input box to sum and display sum as msgbox

    Thanks for the help Roel. My variables do not to save the inputbox as a variable. My msgbox says what is in the quotes and does not pull the data stored. Can you help me understand what I am missing in my msgbox code?

    Re: Input box to sum and display sum as msgbox

    your variables work fine they are storing the values you put in the inputbox. Try using F8 to step thru your code you will see if you are past the first inputbox.
    what you are missing is the difference between a (numeric) value and a string. first you need numeric values to do calculations (look at your declaration of variables) and also the proper use of double quotes is an issue in your code.

    things to do
    1. add a calculation to get the sum of the variables
    2. make minor changes to your messagebox code to show the input and add something to show the sum in the msgbox too..

    Re: Input box to sum and display sum as msgbox

    I'll also agree with both of the above! So as for a little more help...

    Open your Locals window from the view menu and step through your code with F8. You'll see that your variables do populate as expected. So perhaps the issue may be in how you are referring to your variables. Also you should go to a spreadsheet, type ="A1" in a different cell and see what result that gives you, and is it what you'd expect; and if not, why might that be? Finally, a bit cryptic but, what makes a number a number?... why can we do 1+1 but not one+one?

    Re: Input box to sum and display sum as msgbox

    you are really close.. but coding is brutal when it comes to spelling. even more so then in English class 1 mistake and the whole code will fail. But you still have several mistakes.
    still a bit of a blindspot with you for & and "
    you have to really cross all your t's and dot all the i'or in your case all the & and " in the right places
    on hint to keep going forward: only use double quotes around text strings never around variables or formulas.
    really important to get this right on your own. y'll never forget again

    I give you one more push in the right direction. Common functions used in a worksheet like sum dont work in vba, you will need to tell vba you want to use a function with the prefix "worksheetfunction."
    so make sure the sum function looks like this

    and have another look at how you want to add that code to your message box.

    Alex,

    What code doe you have so far ?

    Also use Application.Inputbox with which you can control the input.
    Avoid using Select, Selection and Activate in your code. Use With ... End With instead.

    Re: Input box to sum and display sum as msgbox

    OK, to summarize.
    Text goes between double quotes. Variables don't need to be double quoted. Text and variables are concatenated by the Ampersand eg &.
    If avalable I use the application version of a worksheetfunction because when running code with the Worksheetfunction and an error arises your code goes into Debug while
    using the application version your code runs further but you can trap the error using IsError.
    That being said here's something to study on.

    In a worksheet module.

    In a standard module.
