Why msgbox is not appearing and why items aren't being removed?

Many problems have appeared in my form.

1. I put some "msgbox" to test it. When I run the first time they appear. When I click to open the form again, the messages simply disappear, even though I had written msgbox "why??" in the first line of code.

2. We created a code to remove empty items from the combobox, but they just aren't excluded. They asked that I reversed the "for", to start from the bottom up. Didn't solve.

3. The program is unable to calculate the minimum and the average of a range, although the code is correct.

Someone, please, would be able to help me?

Hi marlonsaveri

I think the problem is that you are not doing an UNLOAD ME on your userform when you close it. This will keep the Userform in memory and it won't execute the Initialize code if it is already in memroy.

You need to study Userform.Show, Userform.Hide and Unload Me.

Change the code you have by adding the Unload Me line below and see if this works for you.

Marvin, as a regular poster I'm surprised that you answered this question that so obviously did not comply with the Forum Rules

Hi,
Try this to get rid of blanks in the combo box. Replace your code with.

Hi Marlin,

Maybe your "myRange" isn't defined or has things in it that can't be averaged. If and when your program stops with the error you should look to see where myRange is pointing and look at each of the cells to see if this is causing the problem. If these aren't cells but in the UserForm, check to see if the userform is open/in memory and has values.

You should also learn to Debug your code using Breakpoints and Stepping through the code which might also uncover the problem. see http://www.cpearson.com/excel/Debug.htm
