hi!
i would tell you to do an apprach with dinamically selectors.
that is:
using the explorer see all information that is related to that uicontrol. ( you can click on it and then you’ll see the control information)
you’ll see some attributes that you can use to do dynamically selectors. for exemple let’s say that you have a direct field like “Name” and a textbox to insert the name. if you explore that direct field you’ll see the id of that field. then click the textbox and try to view if there is a relation of those fields. then if you find that relation you cancreate a variable and fine tune the activity that is having problems… i had similar problems and i had overpass it with what i’ve describe to you.
