comboBox wont send variables

I cannot get any comboBox to send readable variables to the database. Input fields seem to work fine. However the database cannt translate the comboBox fields which appear as .class variables.

I’m trying to find a way to use buttons in a movieclip (combobox movieclip) to change the input text and use that to submit the fields.

Can anyone tell me if it is possible to change input text and how to do it from a button (tracked as a menu item).

tia!!
