Execute query for oracle forms tab pages

Question

Hi Guru's,
Please help me how to work on execute query with forms tab pages. I have created three tabs like A, B & C in one canvas.
I have three tables and I have created three tabs in one canvas. And there is no master detail relationship with these three tables.
I have written the code in form level - when-new-form-instance like do_key('execute_query') but when i see at run time its executing for first tab A not for tab B or tab c.
How to get the data or execute the data in tab B and tab C.
Thanks
RS
