Much appreciated! > > Aaron Lemmie, try that again, (darn webmail and TABS moving to next form element)... FYI - prob. better in the php-general list. But, I think your nested foreach() are the culprit. Assuming $nameRefered = ( 'Joe', 'Bob', 'Jane' ) Assuming $emailRefered = ( 'example1@example.com', 'example2@example.com', 'example3@example.com' ) With your code, you would get emails to the following... Joe <example1@example.com> Joe <example2@example.com> Joe <example3@example.com> Bob <example1@example.com> Bob <example2@example.com> Bob <example3@example.com> Jane <example1@example.com> Jane <example2@example.com> Jane <example3@example.com> I would consider using the following due to the name/email being stored in separate variable structures. for( $i=0, $i < sizeof($nameRefered), $i++){ /* to get this name */ $thisname = $nameRefered[$i]; /* to get thisname's email */ $thisemail = $emailRefered[$i]; } Provided of course that the values in the slots of the array correspond perfectly. -- Ryan T.
