How can I add a dollar sign to the calculated result?

Hi Marvih, for the first question, I do not know where to place $Total:0-9, if you look at my at the Total field, I can't even find the $ symbol?

The dollar sign is not present on the numbers pad in the widget, but this can be manually typed with your keyboard, in order to avoid any interference with your calculation, I would recommend you to add parenthesis to your entire calculation and add the symbol outside: 

You can see the result here: https://form.jotformpro.com/72684556585977 

I hope this helps. 

Thank you but I cannot get it to work, now is not even adding at all, do not see the dollar either.

This happened since your dollar sign was not added as text, I already fixed that and it's working on your form too: 

If you have any question, please  let us know.
