Could not convert variant of type (Dispatch) into type (Integer)

It is telling you that there is a type mismatch between the field that you are reading and what you are trying to do with it in the test.  An object may appear to be a number and not actually be one so when you try to use it as an integer, it will not work. Since the Object Spy says "text block", I expect that is what is happening here.

You can use aqConvert to change types. There are many examples here:
