Nowadays I would start with the "Re-Enter your email address, followed by a numeral, any numeral" -- and you delete any numerals from the end of the emailString put word 1 to -1 of line 1 of emailInput into emailStr1 put word 1 to -1 of line 1 of emailInput2 into emailStr2 set the itemDel to "@" if the number of items in emailStr1 <> 2 then exit --something is wrong get (last char of emailStr1 is a number) get it && (last char of emailStr2 is a number) if "true" is not in it then exit --do both strings in case someone gets confused repeat until last char of emailStr1 is not a number delete last char of emailStr1 end repeat repeat until last char of emailStr2 is not a number delete last char of emailStr2 end repeat if emailStr1 is not emailStr2 then exit --clean up for typos replace comma with period in emailStr1 replace space with empty in emailStr1 if char -4 to -1 of emailStr1 is not among the words " .com .net .biz " then exit --does not look likely checkForHaveAlreadyInDb emailStr1 ------------------------- Obviously I am not in the business of web form security. These are some of the filters I would put in place if I did a high-volume, high-profile site like yours. Hope this helps give you ideas.
