Thnak's for helping me out with this. Well I am trying to build a user form where it takes value from text box for size D and one for length L and I choose a process in a combobox like size, straightness, circularity and cylyindricity which have different formulas and are associated with each other. So when I enter a size and length and choose a process and hit the command button I want it to calculate the value. So D is a constant and ts, ci, cy are all results which I want to be able to calculate . I am not sure if you understand what i am trying to do? But i could use some assistance on this.

The way you describe the process could easily be done on a spreadsheet without using a form.
If you really want to do it on a form, can you give some examples of what you're looking for, like if the user enters 3 in size and 2 in length what will be the answer for each selection in the combobox?

Hello peedarp1985,

Your If Then statements are not working because the data being evaluated is a String and not a Number. All data going into and coming out of a TextBox is a String. You will need to convert the text to a number before you test it. It is easier to read using the Select Case statement rather than multiple If Then. Indent your code. It makes it easier to read and to correct.

Thanks guys I actually solved it. I just had to use double in place of integer which was a silly goof up. Thanks for the help and advice once again.
