Is there a way to format the number field?

Is it possible to format the number field so that it formats with a comma (ex. 2,000 vs. 2000)?  I have a number field calculating a total dollar amount, and would prefer a comma placement when over 999.

Yes its possible to do this with the Masked Input Widget. Search for it on the left. And drag it onto your form:

Then click on the wizard (magic wand icon). And configure your widget how you like. You will need to add a comma for thousandths separator.

Thanks for that!  Unfortunately, I need to have this field calculated, and it seems that the widget won't work with the calculation settings.

Why don't you use a payment integration?

I have made a demo for you:

You can view or clone a copy. Then modify it as you like:

I love this, but the problem with payment integration is two-fold.  First, I'd need the same payment fields for the check payment option.  Second, we currently redirect to our Patron/Salesforce donation page for credit card payments.  While I know JotForm integrates with Salesforce, I've been told by the folks at Patron that the integration doesn't work well with them as your integration doesn't recognize custom objects.

One solution to consider is using the commaSeparate() function which you can access through the options button in the widget wizard:

On the math functions tab you scroll down until you find find that function:

Please note that all your calculations should be inside the function parenthesis in order to have this working properly.

I hope this helps. If you need further assistance please let us know. Thank you.

PERFECT!  Thank you!!
