I am just making a simple script to add peoples names to a data base for a mailing list. the first night i made it I tested it under mozilla and IE from my own apache 2 server at home. Then I uploaded it to the website host and it seemed to work. The next day it seems like when i use IE it skips over the part of code to execute if the email is valid. Now if I remember correctly.... PHP is executed on the server so the browser should have no infulence on the outcome of the code. I dont' have trouble with the variables not containing the right data.. it just seems like IE causes the server to ignore some code.. any help at all would be greatly appreciated...

ps.. this file is called test2.php in case you were wondering what the action part of the form pointed to..
