set the text of button "myComboBox" to theList

Good suggestion, but it crashed.

To get the data that has been typed the code I use is:

No problems with that.

I'm running LiveCode 4.5.1 perhaps this got fixed in one of the later versions? I'll submit a question to Runrev. If I ever get comboboxes to work, I'll post the magic here.
