Combo Box Use Global Data issue

I am using a drop down combo box to select a name, and have checked specifiy item values, am using the item numbers in a switch statement to populate other text boxes depending on selection of drop down.  These same items appear several times in the form, so am setting them to use global data.  All work great except for the textboxes bound using global data to the drop down.  In those results, it's putting the item number, not the text value.  How do I get the text value to show instead of the item value?  Thank you!
