In setting up the calculator

1.  Is there a setting that allows commas to be added automatically 

2.  Is there a setting that adds the USD symbol (currency) to the number entered otr totaled?

I inspected your form and I saw that you are using a Number field. Unfortunately, that is not possible to achieve with a Number field 

It can be done with the Masked Input widget. 

Another way is to use the Form Calculation widget and get the value from a Number field. You can add dollar sign inform of the calculation and use commaSeparate() math function.

Here is my demo form with both options:

Feel free to test it and clone it. 

Hope this meet what you are looking for. 

Thank you for your kind assistance. I am not quite there yet but making progress, it seems you are telling me to use the masked input in lieu of the number and the form calculator for the summary .
again thanks

Hello Thomas,

The initial suggestion that BJoanna had in mind was the masked input widget.

She suggests a second option by using the form calculation widget. I would also go for this method, since I find this more versatile.

In any case, feel free to let us know if you have questions or if you need assistance.
