Question : Entries with Commas Not Generating Value in IE/Javascript

I have some code that calculates a form field based on the value of three others if they aren't null.    The entries in the form are automatically formatted with commas to make it easier for the people to view their entries.    I strip the commas out of the values before doing the math and this works just fine in Firefox but as soon as I add a comma in the values in IE, the script doesn't run.   I don't get an error withe debugging on, it just doesn't update the total field.    I tried alerting once the entry was made to see what was being passed but it doesn't work to even do the alert.
