Validation Script

[stfarm]

I have a couple of questions. How can I validate check boxes, radio buttons and drop downs???? I hope you can help me with that. Thanks.

(i hope you realize it will be a real pain for users to fill you form, as they'll get warned one error by one error !!)

validating checkboxes : formname.checkboxename.checked (true if checked, false otherwise)
validating radiobuttons
same as checkboxes
validating drop down
formname.selectname.options[formname.selectedindex].value
