How to parse profile field of type multiple line text box?

[thisgeek]

I've got a multiple line text box profile field where users can enter various values, one per line. Is it even possible?

How do I parse the text box so that I can output one line at a time?

If I refer to the text box as $post[field24], then it outputs everything in one line (I'm trying to use the field in a tooltip, so it shows the carriage return/line feeds as block chars).

Thanks.
