Description	This expression will validate for US Currency with a wide range of input. Using other exps found on this site, I built this one to fix 2 main problems I was finding: 1-a space or blank entry is non-matching 2-use of .9 in place of .90 will match (this is for those people like me who hate to type and if I put .9 I mean .90 Hope this helps others save a little time. I feel I was pretty thorough in testing, but if you find something wrong, please post it. -Thanks
