modified profile.php does not recognize custom $_POST['do'] == "xx"

[محروم.كوم]

Hi

i modified the profile.php and added a new part

Quote:
if ($_POST['do'] == 'ptbank')
{
header('Location: profile.php?do=whyisitnotjumingtothis'); //







Bank



$vbphrase[tp_info]







$vbphrase[tp_info2]


$vbphrase[key_text]

Key:




$vbphrase[spamfilter_notice]



























if i call now profile.php?do=bank, then the template will be shown correct, if i enter a value and click submit, then it will always insant go to profile.php?do=bank again.

I dont understand why, where is my mistake?
What am i missing?

I hope someone can help me __DEFINE_LIKE_SHARE__
