Variables not working with Export Wizard?

Hi, i need some help to understand the way Toad works in this matter.

I need to create a loop dataset and with every result (binded variables) send a different excel and activate a macro on that excel.

I find that if i use a 'loop dataset', then i cannot create an 'export wizard' inside with the binded variables from the loop. And if inside the loop i use 'select to file' i cannot trigger the macro because the screen to trigger macros doesn't appear...

Why can i not use the binded variables in the export wizard or why can i not trigger a macro with the select to file???

I'm trapped in here...
