Hide/ show a recordset row item
Making a page to display a resume. If a category or row is empty or null ..do not want the the title to appear. using dreamweaver's detail generated recordset. This is one example: nothing displays , regardles if there is data or not. What is wrong? or a suggestion of a better way.
Thanks

that was the trick...thanks!
Notice: Undefined variableAs soon as you understand what that means, you will be able to move to the next level! Until then, well, not so much.
Best of luck and thanks for using EE, ~Ray
var_dump($totalRows_Detail
var_dump($row_DetailRS1);
Once you can see the data, you will be able to know what path in the code will be dictated by the if() statements.
Be certain to add error_reporting(E_ALL) to the top of all your scripts in order to avoid accidentally relying on an undefined variable.
