trying to modify product options PowerStore300

I'm trying to modify a products options in the store (PowerStore30) Manage Advanced Options and I am getting a warning message when I delete an option from the list, see below:

Warning: Cannot modify header information - headers already sent by (output started at /hermes/web###/b1067/server/PowerStore300/Admin/options_Add.php:51) in /hermes/web###/b1067/server/PowerStore300/Admin/options_Add.php on line 425

Line 425 is:

header('Location: options_Add.php?ProductID='.$_GET["ProductID"]);


Not sure why this is going on, I had 12 options in 1 dropdown and am just deleting some of those options.

Ann suggestions?

Thanks

I decided to delete the entire option and got this message:

Warning: Cannot modify header information - headers already sent by (output started at /hermes/web01b/b1067/moo.scmeyer/PowerStore300/Admin/options_Add.php:51) in /hermes/web###/b1067/server/PowerStore300/Admin/options_Add.php on line 482

I should also mention in bothe instances of errors that the CSS is thrown off with regard to link styles and alignment.

The headerrs already sent error means that there is some sort of output occuring on the page before the header function is used.


the error is reporting that the outpu started around line 51 of the options_Add.php page:

output started at /hermes/web###/b1067/server/PowerStore300/Admin/options_Add.php:51


if you are having dificulty locating the problem, please send a copy of the options_Add.php page in a zip file.

Sorry Jason but I'm not seeing it. I'm not much on PHP but learning, my guess would be it's further down in the option statements but I'm not sure. I am attaching the zip file of the page as you suggested.

Thanks for your help!

line 50 has a blank space at the end:
"?> "

that is causing the error.

delete the blank space at the end of line 50:
"?>"

Okay, I know I wouldn't have even consided that!

Thanks for the help.

you're welcome.
