Error adding a collection filter while mapping a template document
I'm currently following the process automation 1 self paced course. In the solution to exercise 4 (how to create the "Issue travel advance..." ) video, at slides 64/95 I'm asked to add a collection filter while mapping a template document. At that point I get an error message stating : "Input string was not in a correct format". I then have choice to save (to save the whole error code) continue (it works but the error remain) and quit (which kills the application). So with that error I can't define the filter of the collection.
Anyone has ever saw that problem and could help me with it? Juan Zuluaga could you help?
Muchas gracias para la ayuda.
