Forcing a client side event to output a number to 2 decimal places

    I have 2 fields on my form that does some simple math to pass a dollar amount to an external form.

    Example:

    Field asks how many guests are attending, user puts in 3. A client side event (specifically: $(amount) = parseInt($(attendees)) * 15.00) multiplies that number and passes it to a hidden field ($amount) that gets passed as a querystring variable to the external form.

    Make sense so far?

    That client side event works perfectly, however the output doesn't have any decimal places to make it look like currency. Is there a way to force the sum of the equation to 2 decimal places (ex: 15.00)? I'm no good with code, I had to find an example of this client side event on another form and modify it for my purposes.

    If somebody could help me out i'd be very appreciative!

    Thanks.

    Hi Josh,
    In the client side event you need to properly apply a conversion to currency. Take a look at this link: http://javascript.internet.com/form...ormat.html

    What you will find is that formatCurrency(this.value) in the site would probably be something like this in your code:
    $(amount) = formatCurrency($(attendees) * 15) as my test didn't need the parseint. The thing is you will get a $ x.xx type of result when you convert to currency so you won't get a x.xx look i.e. without the leading $ sign but that is how javascript looks and that is how currency looks. Hope this helps

    Don,

    Your code worked as described, but the 3rd party form rejects the $ symbol that gets passed. Oh well! What I have now works, it was mostly a client nitpick that I asked.

    Thanks so much for your reply! I appreciate it.

    Josh
