Using a string from a custom field within a link

I want to show the image only if there is info in the field. And the link around the image uses the info in the field. The mailto: field is coming up blank. So I'm guessing/hoping I'm doing something wrong with the way I'm printing/calling it. I would greatly appreciate any help.

?php $email = types_render_field ("email");
          if ( $email ) { ?
           a href="mailto:?php $email ?"img src="?php bloginfo( 'template_url' ); ?/images/icon-email.gif" width="24" height="24" //a
?php } ?

In case it's relevant, I'm using the Types plugin to create my custom fields.

Change,

<?php $email ?>

to...

<?php echo $email; ?>

as you need to echo the result of what's held within $email as the function types_render_field would be using return within the function (if you dig into its core) to return the data instead of directly printing it to screen.

<?php $email = types_render_field ("email");
          if ( $email ) { ?>
           <a href="mailto:<?php echo $email; ?>"><img src="<?php bloginfo( 'template_url' ); ?>/images/icon-email.gif" width="24" height="24" /></a>
<?php } ?>

I figured it out! It had to do with the way the custom field had been created. When it was an "email field", it gave me that big mess. When I made it just a single line text field, it was fine.
