Filter data using 2 selectors

Hi there,

I'm struggling with the following problem :

I have a list of projets for which I display, for a selected year, the budgeted invested amount and the actual spent amount.

For a given year I only display the projets for which the budgeted amount is greater than 0.

From this projects list I need to let the user choose the ones he actually wants to display.

However I'm not sure how to display the restricted list of projects (those with budget<>0 for the chosen year) in the selector.

Thanks in advance for your help !
