Trying to

1. select all points by location  that fall within a polygon
2. select by attribute from the selected by location using an expression. so far it works fine  ..
3.  I have a list of values -  I need to change the expression  every time the model run  and write the results to Excel or Text File  as table  as follows.

        call_type    -   Count
 
I know that can be accomplished using the iteration  but I couldn't figure it out.
