LoadVars.sendAndLoad() ... again

I don’t get it to work!
Can’t someone please post a link to a tutorial where I can read about LoadVars.sendAndLoad() so that it will work for me?
I’m getting nuts over here in Sweden… :d:

What I want is to 1) send at least one variable to php, to get php to store it in a mysql db (this i know how to do) and finally 3) select the same variable and send it back to flash.
all this with the sendAndLoad.

I’ve managed to do everything but returning the variable from php to flash!

Please, someone…
