So, I changed my form method content ( thisform.z_CN() ) to :

RETURN (["CrsSel]+PADL(ALLTRIM(STR(thisform.PageFrame1.ActivePage)),2,"0")+["])

and command line to :

      replace TkCode WITH 1 IN EVALUATE(thisform.z_CN())

but i get Invalid subscript reference error.
what about this command?
thanks
