Customize email subject with data from form fields?

Hi, I've built a form that captures info in to a db and then emails the form contents to an array of recipients. All is working fine, however, my client informed me that they would like some data from the form to be included in the subject line. Currently, all submissions have the same generic subject line. Looking at my form page, I see this:

$_SESSION[$EmailRef."_Subject"] = $GLOBALS[$EmailRef."_Subject"];

But, I also see places in the waeu insert PHP page as well as the template PHP page that got created where the subject is supposedly specified. Hence my confusion. Any suggestions?

Thanks in advance!

The subject line is set on the first few lines of the included email file. This line is not significant in terms of updating the value.

Thanks, Ray. I see the following line in the waue insert php file, which I've previously customized with my generic subject:

$MailSubject     = "New Request Received";

I'm just not sure how to modify this to include one or two of the data fields since that file doesn't seem to contain any db connection info, just the email configuration stuff. Normally I'd include something like "echo($row_WADAmy_table['my_field']);" but I can't imaging that would work on this page for the aforementioned reason. Any pointers on where/how to pull field data into the subject line?

Thanks,

Data from the form is referenced like: $_POST['FormFieldName']

So including data from the form into the subject would be done like:

$MailSubject     = "New Request Received from " . $_POST['FromEmail']  ," using the online form";

That works perfectly! Thanks for your help, Ray.
