I am having problem display text in a checkbox where I want to display different text depends on the value passed from the Stored Proc. 1.e, I have chbBox1 and txtChbBox1, my formular for the chbBox1 is
IF {SEDA_PRC_CR_PO.CR_TYPE} = "O" THEN
(IF "11K7010" IN {SEDA_PRC_CR_PO.CHANGE_ITEMS} THEN X:=TRUE);
IF (LENGTH({SEDA_PRC_CR_PO.CHKBOX12}) > 0) OR X then
" X"
else
" "

and my formular for txtChbBox1 is
IF {SEDA_PRC_CR_PO.CR_TYPE} = "O" THEN
"SVD UAE MDC 11K7010";

I want to display and check the same box when the value is "SVD MDC S32300-28". How do I implement this. Thanks.
