I try using this:
print("Descr.: ", txtExprDef:GetDescription() )
to get the Description of an item in the "Miscelaneous" category, but get
an error:
[string "--------..."]:43: bad argument #1 to 'GetDescription' (FCString
expected, got table)
I do not understand, why a get method needs an argument? Why is there a
FCString parameter necessary? And how can I retrieve the value of the
description field of a expression tool item?
Thanks!
