perzie23, you need a couple things. First you need the code to do a call with "sendAndReceive" (not sure which class/function it is) to actually send the data. You also have to get the values of the inputs, rather than making them the default. Usually that's done with:
var name = _parent.t1_2.value;
or something of that sort.
Then you need a php file to take the sent variables and create an email message and send it out using the [man]mail/man function in PHP.
If nothing else, I know flah-db.com has some really good tutorials on doing just that.
