Thank you Lee for clearing that up. Where would we be without you!
In BC this function is currently not compatible:
for the min and max arguments you can use any number (even a real) but NOT a quoted variable.
I did search theswamp for this (of course
) and found this bit of code:
(vla-ismergedcell tab lig col 0 0 0 0)
As you can guess BC has no problem with this. But how does AC cope with those four zeros?
