Hi All,
Trying to get this regular expression working.



I'm trying to have a regular expression that takes a number to determine how many decimals it wants in $1 and the rest should go into $2. Basically I have a number like 35.69. I find the position of the decimal and then any 4 digit number a user enters has to be reformated to look like the number specified (in this case 35.69). What I'm trying to do is take the index of the decimal in 35.69 and then use it within the previously mentioned code to grab first N number of digits and put the rest into $2. Each time I run this I keep getting only the second digit in $1 (in this case 5.69, if Answer was 95.67 Answer would end up being 5.67, etc..,). Any help would be appreciated. Thanks in advance.

Rob
