UBB.Developers Forums Community Development Programming PHP and Server-side Scripting How do the make the RETURN key return?

I have been playing around with perl for a qhile now and one of the things I love about the UBB which so far I have been unable to figure out is how do UBB make it so that when the RETURN key is pressed it shows the new line in the final post?
Basically what happens when I try this is I put up an input box and whilst it all looks great in there, when it comes to viewing the post all the words are wrapped one the same line (i.e. the return paragraphing has been cancelled out).
Does anybody know how to fix this?

Thanks in advance.
