I know how to basically set up the format for $msg such as:
$msg = "First Order: $tops_1\n" .
"Name: $name\n" .
... etc. What I need to know is how to concatenate variables on one line if need be.
I would also like to know is how much freedom there is to format the $msg output in other ways and the formating/syntax to do that. I know that \n creates a line break and I think \t creates a tab space but I'm fuzzy on everything else. I hope this is clear but if not, let me know what more information you need.
