Morpheus,
You're not enclosing the text field's value in quotations. Same rules apply with PHP as HTML when it comes to form fields (you know, seeing as how it gets sent to the client as HTML🙂. Try this:
<?php if(isset($phone){echo "value='$phone'"; } ?>>
or this:
<?php if(isset($phone){echo "value=\"$phone\""; } ?>>
All your input should show up just fine. HTH.
Cheers,
