问题
I am creating a "Voting system" and i have problem on the ballot form. Every time i choose candidate in my combobox, the rest of the combobox will also change.
here is my ballot form..
and when i choose my President candidate in my combobox1 this what happens..
I guess its because of my 'Candidate' table?? My issue here is how can i filter combobox1 like for example... listing All "president candidate on my combobox1. without affecting other comboboxes.
PLEASE HELP Im a student and my Thesis defense is on Friday ... LOL
