How to create a reliable calculated field with currency symbol?

Hello, 

Please Show me how get a relaible calculated field please.

When I write 

Quantity = 3

Price per unit = 11,11

TOTAL = 3333

I tested 3 ways...

1st way, I used "maked input" field to have dollar values, and make conditions but total field doesn't appear...

2nd way, I used basic field but total is wrong when I use comma for decimal separator (Field : price per unit # 2) and I can't ban comma in this field... 

For exemple :

Quantity # 2 = 3

Price per unit # 2 = 11,11 $

TOTAL # 2 = 3333 $     ????  (you see that...)

3rd way, I used Form Calculation Widget, but it looks like 2nd way. 

If you use the point like separator it is ok but not with the comma... 

However users are allowed to write in 2 ways...

It doesn't matter if we use comma or point but if we must use the point, please show me how to ban comma option (in field "price per unit") ?

Also It could be interesting to have $ symbol in fields.

Thanks a lot for your help !

Please note that you can add a textbox field for quantity and "Masked Input" widget for price per unit. You can then add "Form Calculation" widget to calculate the total amount. You can also add "$" in form calculation widget to display the currency symbol. You do not have to add any condition for calculation but just add the form calculation widget to achieve your requirement. Please check the screenshot below:

Thanks for your answer, 

Last things, I'm not able to make the 3rd field (result) just read only.

Despite select option "Result field is read only ", I am able to change result.

thank you for our help.

Have a nice day !

If you select option "Result field is read only" of form calculation widget, that should solve your problem. I enabled it in my test form and I was unable to edit the value in form calculation widget of form. Please check the screenshot below:
