onchange

[deniz]

Hi,
I want to make a php document and I have a combobox which has user names and I have checkboxes after combobox.I want that, some checkboxes would appear some don't, changing to which value chosen for combobox.As I learn I should use onchange function but I don't know how to do.
Can u help me?:o

As this is a JavaScript issue rather than a PHP issue, I've moved this to the Client Side forum.
