You should read up about [url=http://uk.php.net/manual/en/ref.errorfunc.php]error reporting[/url] within php.

Also the [url=http://uk.php.net/manual/en/function.error-reporting.php]error_reporting()[/url] function

I still don't get this.
If you just supress error does that mean it still won't work properly.
Do I need to fix the errors and why did they come up anyway?

[HuggieBear]

OK, my advice would be to add this line to the top of your script, just below include("dbconnect.php");

[code=php:0]echo $_GET['alName'];[/code]

Does it output the value you're expecting?

It all works fine. The file snlCombo is part of a flash script which calls it.

flash part

send_lv.alName=combo1.value
send_lv.sendAndLoad("http://jagguy.ej.am/flash/snlCombo.php", nameVars, "GET");

You wouldn't run the file on its own as it expects a value and returns a value. Now on my machine it works fine so whats with these errors, and is fixing this means this will work properly on another website anyway.

I'm fully aware of that, but by adding the line I suggested and running the code again, you'll be doing some debugging.  Identifying if the value that actually gets passed to the php script from Flash is actually what you expect.

The thing is is that it does pass the value correctly on my machine. On my machine it was thouroughly tested in all aspects. I never would port a program without testing such things.
To have the same code fail on another website is confusing. I will have to create a smaller program and test it on the other website with just sendnload from flash.

Obviously there are a few time consuming quirks  here.

thanks for the replies by the way.
