Adding some modification code creates an error

[Chrisj]

I'm trying to add a Member Credit modification to a php file, that works successfully on another site. I'm trying to figure it out as I go, When I add some of the lines of code into the search.php file I see a HTTP Error 500. But when I commented-out these lines:

//CREDITS MOD

//--BEGIN--

$video_price = videoPrice();

$total_price = $video_price * $total_records;

$member_credits = get_member_credits($user_id);

// --END-- 

the file proceeds successfully. So, obviously I'm missing something. Can you tell me what the function of these lines might be? And maybe what might be needed? Or tell me what these lines might mean? Any help will be appreciated.

The only way to find out what's wrong is to actually check the PHP error log on your server.

 

We can only guess. Maybe one of the functions is misspelled or not included in this particular script.

if you turned error reporting you could see the error message
