Could you post some excerpted code please? 

You seem to have multiple issues:
1 communication between a 'mainline' and INCLUDEd code
2 communication between a 'mainline' and a function
3 working with scalars and arrays
4 working with text strings and ?text arrays
- which may or may not be related/relevant

Let's start with simple ideas:
0 put debug echo statements into the function (or everywhere) to track progress
1 if you take the processing code out of the INCLUDE file and put it in the 
'mainline', does it then work as planned?
2 do you have an & to indicate a pass by reference cf a pass by value (see manual)?
3 and 4 does the processing use tools/approach/functions that only work with 
A process of elimination...
