New User Script Failing Unexpectedly.

Okay, this is a tricky one (i think so, anyway!), and rather long but pleeeeeeeease help me! I don't expect you to spend hours looking at the problem, but any insight is appreciated. I am (trying) to create a members only website. However, I am having a spot of bother. It all works perfectly... The second time you fill in any form. first, the user goes to newuser_process.php (Sample A) (the same thing happens if the user goes to apply.php, I might add). Then, the user fills in the form, and submits it to newuser_process.php the program then checks for blank fields, which it finds none. it then goes on to check individual fields, and here it hangs. it executes the if block (even though the condition is not true), and re-shows the form, with the error message, but with nothing in the fields. If you fill in the form again, it works. help!!! So far, I have re-arranged the validation order, to see if that makes a difference, but it always fails on the first if loop. I have also tried to manually recreate the variables on sample 'B' (apply.php) (shown in green, if you have html formatting enabled. Other than that, I am totally clueless. You can reach me at any of the adresses at the end of the e mail, for any solutions, queries about my aims/ideals in this script, or anything else. P.s. The .inc files and .js files are totally unrelated to the newuser script. Thanks, Adam Bishop Sample 'A' <?PHP switch (@$do) { case "process": session_start(); session_register('Sauth'); session_register('Slogname'); session_register('Spermissionlevel'); session_register('Sapprove'); include("thing.inc"); foreach($HTTP_POST_VARS as $key2 => $value2) { $$key2 = $value2; } foreach($HTTP_POST_VARS as $key => $value) { if ($key != "address2") { if ($key != "mobno") { if ($value == "") { unset($do); $message_new = "You have missed a required field.
