I&#039;m using a Custom Validation Control in ASP.NET and am trying to write the regular expression to recognize money. The entry may or may not contain $, it may or may not contain comma&#039;s, it may or may not the cents(.##), and it must have at least one digit. So this is what I came up with (I have no previous regular expression experience and it will probably show)<BR><BR>$?[0-9]+(,[0-9]{3}]*(.[0-9]{2})?<BR><BR>I&#039;m trying to say <BR>0 or more $<BR>1 or more digits from 0 to 9<BR>0 or 1 comma&#039;s followed by three digits 0 - 9<BR>0 or 1 period&#039;s followed by two digits<BR><BR>Its not recognizing anything that I try .... Any help is greatly appreciated. <BR><BR>Thanks.<BR>
