Form validation - without onSubmit?

[Jon99]

I have inherited an application that uses embedded perl which I am trying to enhance (not rewrite!). I need to ensure that all form fields have been completed before the form is submitted - If submit is clicked the values in the form are evaluated and (if incomplete) an sql error is received. The form comprises both select and text boxes - therefore onBlur cannot be used on text boxes (?).

Could I have a verify button which evaluates the form and then reveals the submit button if validation is successful? How would I do that (could you point me to a resource if such exists). Any other suggestions?

Thanks, Jon

I might well be able to - may well have not been using onSubmit correctly previously! Currently trying to test it out again - thank you for your reply.
