Placing content via DWMX pop-up menu

On 1 page I have 3 JS-pop up menus with 3 choices each. In MySQL I have 1 table with 9 records with 'txtID', 'txtitle' and 'content' and a recordset that shows all records. (SELECT * FROM dbasename WHERE txtID = colname and in the variablebox colname  1  $HTTP_GET_VARS['txtID'])

By clicking the pop-up menu-items I want to place each of the 9 txtpieces in a layoutcell and the 9 titles in another cell with recordplaceholders on the same page.

Can anybody help me with the code I have to put in the link in the Designbehavior "show pop-up menu"? It seems I can't pass the value of the txtID to MySQL.

It sure would brighten up my days and nights! Thanks in advance
