Have you ever tried to add up multiple fields with JavaScript, only to find out that the client entered a comma to separate thousands and millions? This causes JavaScript to drop all of the digits after the comma. You can use the split command to extract the commas prior to adding the fields together.

Add the removeComma function to the JavaScript Header section of your form, then add the call to the function, onto the onBlur section. Now, when the client moves from one field to another, all commas will be removed from the field.

MEMBER FEEDBACK TO THIS TIP

I've found this works as well.
