**stephie6**when customers make a checkmark in the the text box for "avec changement" or "sans changement" the price appears autmatically. is it possible?

**Carina**Please provide more details on the desired result. Will it have a calculation associated? If so how is it performed?

But you can add a Form calculation and then add calculation values to the checkbox field so that it retrieves a value upon selection. You can test it here:

**BJoanna**Unfortunately it is not possible to clone fields with conditions and calculations from one form to other. You can follow instructions provided by my colleague to make calculation inside of your form.

It is possible only to clone fields without conditions by using Field Manager.

More about how to perform calculation in the form you can find in this article:

You can clone mentioned form http://form.jotformpro.com/form/51066045906958? to see how calculation are set inside of the form.

Hope this will help.

**BJoanna**It is not possible to pass filed values to drop down field. Instead of drop down field you can add calculation widget and than pass values from check box field to calculation field.

You need to add Calculation values to check box field.

These values will not be seen but will be used in the calculation field.

Now you just need to add the checkbox field to the calculation field:

Also you can rename the label of calculation widget.

Here is clone of your form that I have change.
