Hi Lambert That's because you don't know what you are doing! You deal with the SSN as if it was a number which it isn't - it's a string. Thus: SSN = Format("123456789","&&&-&&-&&&&") "123-45-6789" confuses Format as it believes it to be a negative number. This, however, will format "correctly": "-123-45-6789" but is that less weird? I guess not. Your method of removing any non important character like space and hyphen before applying the format is the proven method. /gustav >>> Lambert.Heenan at aiuholdings.com 16-07-2009 23:14 >>> Here's another oddity. I have been using the Format() function to ensure that Social Security numbers are consistently stored to a text field with the hyphens included: nnn-nn-nnnn. (I know, you can use an input mask for that, but it does not consistently work) So this code should take care of that SSN = Format("123-45-6789","000-00-0000"), and that does indeed give the result "123-45-6789", as does SSN = Format("123456789","000-00-0000") But what about Format("520-09-0012","000-00-0000")? No that does not result in "520-09-0012", but rather it produces "-000-50-3778" - go figure. My solution to this problem is to first strip out all the hyphens and then put them back with... Format(Replace([SSN],"-",""),"000-00-0000") But what are those bizarre results about? Lambert
