hi there

i have three listboxes on my form

lstES, lstNES, lstGC

actually all the three listboxes are aligned one next to the other
The listboxes contains different subjects in each one of them

Actually when i am selecting an item in any one of the listboxes, i wish to have the selected index = -1 in the other two listboxes.

i have tried different codes, but i couldnt possibly make it out. Can anyone help me plz.

Thanks
