Form Builder syntax issue

[benz1]

I've inherited a site (v1.9.3) that uses Form Builder 0.5.11 and CMS Mailer 2.0.1 for it's contact form. It's set up with a "*Call A User Defined Tag With the Form Results" field type to send the email via a user defined tag. The email is received ok but the fields are missing. The relevant part of the tag is:

Code: Select all

Name: '.$_POST['m3fbrp__17'].'<br />
Email: '.$_POST['m3fbrp__18'].'<br />
Comments: '.$_POST['m3fbrp__19'].'

I've added an Email To field type which I receive ok to a Gmail address including the fields but it's not getting through to the client. The email template fields are"

Code: Select all

Name: {$fld_17}<br />
Email: {$fld_18}<br />
Comment:<br />{$fld_19}

Can anyone advise what the correct syntax should be for the Sendmail User Defined Tag for the fields to appear in the email?

Thanks in advance.
