My code isn't working, and I get no errors!
First and foremost: Turn on error reporting at the very beginning of your script.
If you have MySQL queries that aren't working add some error logic to find out why. See the manual
for some examples.
Also, be sure output buffering is off: ob_end_flush()
And if you can't figure it out after that, post a new thread in this forum with as much relevant information as possible, and any code that we might need so we can help you as quickly as possible.
