I want to store the regular expression string to validate emails in my web.config file so that it&#039;s not plastered throughout my site. The string contains amersands(&), which makes my web.config file fail and my whole app won&#039;t work. It gives a configuration error &#039;An error occured while parsing EntityName&#039;. Does anyone know if there is a workaround for this or does anyone have another idea of where would be a good place to store the string?<BR><BR>Thanks,<BR>Sara
