We have a client who needs a web form that assigns a registration number as part of the submission process. So the web site visitor would fill out the form with their contact information, hit submit and then get an email with their registration number confirming that they have completed the registration process.
In addtion my client would get a copy of the submission, also.
We would also like for the submission to write to a text file so the client has a back up copy of all submissions.
Should be a pretty simple form and script. Ask questions if you need more info.
