I have a web service set up that transfers a listing of locations to a combo box. When I change that combo box, I want to fill in an expression label which shows what was selected in that combobox. Unfortunatly, the label is displaying the ID of the combobox and not the value of the box.

Any ideas how I get the Name value and not the ID?

I just wanted to clearify that last statement to make it a little more understandable.

I have a webservice that returns a listing of values, which a combobox on my form is set up to recieve through a webservice.

The combo box lists the values as their literal name value, whereas when I go to grab the information out of that box to put into my expression label, it comes back as the GUID.

How can I specify the label to grab the s4:Name and not the s4:Id. When I try to edit the xpath --

from

my:PayloadFields/my:GenericCode/

to

my:PayloadFields/my:GenericCode/s4:Name

it throws an error saying that it's an incorrect xpath.
