I have built an Addin that has four combo boxes and a button.
combo box 1 provides a list of layers in the TOC (working)
combo box 2 takes user text input for a unique ID field (working)
combo box 3 provides a drop down with a list that displays all the fields in the selected layer (from combo box 1)
combo box 4 will provide a list of all the values for the selected field (from combo box 3)
Combo box 4 is broken, and when I click in the drop down window the python windows displays the following error:
>>>
AttributeError: value
>>>
The scripting is posted below. I can add the rest if needed. Thank you all very much for the assistance.
