dont understand what you mean.
If I use your first SMath Studio worksheet with the latest workbook it seems to work for me.
smath worksheet from
post #1:
Test_#1.sm (8 KiB) downloaded 24 time(s).excel workbook from
post #18:
Wallthickness.xlsm (93 KiB) downloaded 28 time(s).This works for me.
In your latest worksheet
- first import function name ends with "M" instead of "X" in the subscript that is a function not defined
In post #18 you changed the content of the SMath worksheet.

This is the typo I was talking. As you correctly wrote in first post, it should be:

- in second import the column A of the excel worksheet returns several circular reference exceptions (there aren't stored values even opening it with excel and the plugin isn't able to calculate one... I might return 0 or the cell formula...)

This is the new range you are trying to import in the SMath worksheet #18. The range rewritten top-left:bottom-right is A5:G150. The plugin fails loading the first column (I see a circular reference exception in the debugger, thrown by the ClosedXML library), that is something I'll look into.
