How to perform a form calculation using dropdown menu.

I try to make calculation between two dropdown menu, each one numbered from 0 to 10.

It seems does not works for me. You can see in the attachment what I want do do. What am I wrong?

 

Thanks for your support.

Thank you for contacting us.

Since you have the Drop Down options listed as numbers, you can delete the Calculation Values and it will still work. Alternatively, you will need to add a 0 option to the Calculation Values to have a correct calculation order (empty Drop Down items need the value too). 

Also, there is some problem with the Drop Down tags (first two Drop Downs). I would like to recommend you to update the field name tags. Then, you should be able to use them in calculations.

Please give it a try and let us know if you need any further assistance.

Yes, that the first thing I have tried, but calculation field result is
alwais 0. Could you please show how to have teh correct result on the
calculation field?
Thanks a lot for your quick support.
Laurent.

There was indeed something buggy with your fields.  I replaced your dropdowns with new ones and set the calculation up once again.  After replacing the fields the calculation worked.  Here is the form with the fields replaced:

You can clone it to have the updated fields and calculation:
