when making an email, how do you create more than 1 line?

I want to send an email, which I can do. But, how do a make the content of the body more than one line.

so, if I have this, how can I add another sentence 3 lines down?

set bodyvar to firstname & “,” & " Thanks for being a part of our website! Come see us again!"

You can simply use return characters, bonedoc:

set bodyvar to firstname & "," & return & return & " Thanks for being a part of our website! Come see us again!"

thanks!
