Thanks to the suggestions, I use number_format($my_number, 2) to format the number in an edit field. Now I need to reenter it into MySQL. How should I use preg_replace to remove the commas? This removes the commas *and* the decimal point: preg_replace('/\D/', '', $str) In reviewing patterns, I cannot find the purpose of the "/" character in the above. Many thanks.... Todd

the / in above is the start and end token. for every preg_* function, this is used. You could replace it by any other character as long as it is the same for start and end. so above could also be preg_replace('%\D%','',$str); I use % nearly allways, because i like it, and it isn't used a lot. / might be used in paths and can get confusing when \ also used.
