Well... I'm ready to tease you, SheriR, :-p but only because you asked for errors in your parenthesis! In line 18 you made happylab equal, regular, and used and. In line 8 and 16 you capitalized cotton. It's just my software testing quality assurance class coming out! I'll be so glad to be done with college! :-)
(You always do a great job! My posts are always full of errors. The other day I ignored the spell checker red underline for 'humor' thinking, hey!, isn't adding a 'u' just British?)
