validating fields
I have a form which collects detail and then emails the details to an address.
I would like to validate some fields and wonder what is the best way to do this.
At the moment after the form I have a thankyou page but I believe I read that the validations need to be carried out on a page after the action page.
Is there a tutorial on this. I looked for a video but could not find one.
I have attached a zip copy of the file
Many thanks
John
