How do I: City, State Zip

[nscherneck]

I have a form that has three seperate text input boxes with the ID's:

city
state
zip

I want to receive the data from these text input boxes and send it via email. I want to format it as:

City, State Zip

I have this so far but it isnt working, I get a parse error:

$location = "City:\t".$_POST['city'],.$_POST['state']."\t\t"$_POST['zip]."\n".

What am I doing wrong?

$location = "City:\t".$POST['city'],.$POST['state']."\t\t"$POST['zip]."\n".

$location = "City: ".$_POST["city"].", ".$_POST["state"].". ".$_POST["zip"];
