Is there away I can pass a variable from sender (A String Grid) to a sub Procedure. When I try I get a:

  "main.pas(264,86) Error: Only class class methods, class properties
and class variables can be accessed in class methods"

This is from the procedure called by an event and I need to do this multiple times and having it the main procedure is bad programming, makes a larger app and will be harder to debug.

Code please? The error indicates that you're accessing instance members from a class member.
