Thanks for reporting this. I will have a look at it tonight.

[MDoerner]

I think I found the problem, but I will have to verify later.

In my last two PRs, I changed how part of the resolution of index expressions works and introduced a bug: the check that arguments are present was dropped in the part leading to the default member resolution. This leads to a default member resolution pointing to the default member returning a String, the name of the pivot table.

Should I be able to confirm my analysis later, there should be an easy fix.

@MDoerner does it enter the index expression pipeline with Set PT1 = ResultsPT instead of Set PT1 = ResultsPT()? The parentheses shouldn't be needed here, this looks like it could be an edge case.

[MDoerner]

This is not an edge case. Personally, I always add the parentheses to distinguish function calls from variables.

Moreover, the resolution was correct before my changes.
