I'm trying to reach out to a calendar, look for the item with the number 10 inside of column ABCD, and then tell me the item ID for that item. 

I'm using a workflow that calls a web service to reach out to the target list.

I'm obviously doing something wrong but I have no idea what it is. Someone, please help me out here.
