Not clear for me:
1. Here is the first code:

with thisform.GrdInvRes
   .RecordSource = "xtabresult"
	   .SetAll( "DynamicForecolor", "thisform.RowColor()", "column" )
	endwith

2. Here is the second column:

local lnColor

do case
   case ...
      lnColor = rgb( 255, 0, 0 )
   case ...
      lnColor = rgb( 0, 255, 0 )
   otherwise
      lnColor = rgb( 0, 0, 0 )
endcase

return lnColor

Here is the problem:
The genxtab column count can be 4, can be 8 and can be 5 etc, and every time with diffrent header names.
How do I speak with grid values?
What need I write in the cases?

case ? = 'aaa'    &&?- grid value
this?=(rgb)250,250,11  &&?-grid header name
