Wrapping text on a long label

Hi, I’ve got Fast Secure Contact Forms configured for a volunteer signup page I have at:
http://vvamesquite.com/wall/volunteer/

As you can see, some of the labels are long, and the text doesn’t wrap to the next line, it just runs off the screen.

Can you tell me how to fix this? I tried simple HTML within the label, but didn’t work.

Thank you!
