Dear Williams,
My request is straight to you only

I have two tables in my rptd file. Out of the two tables I want to display only one table depending upon the value of flag. If the extensionColumns=1 I want to hide the first table (id="2455") otherwise i want to hide the second table (id="2216"). I have browsed all the other related FAQs about the similar topics and fallowed all the possible solutions given by you.
For your reference i have attached rptd file. Please have look and let me know what could be the issue.
Thanks in advance.
