Prepopulation by URL: Calculated value not forwarded to the second form

Pass calculation is not working on this form even though the URL looks as if it is correct

https://form.jotformeu.com/61913222737353

The question IDs like this 'q3_' should be removed from the field names. Please try with the following prepopulation URL:

https://form.jotformeu.com/61914588258367?myProducts[price]={input61}

Thank you.

It just comes up with {input61} in the box. It doesn't seem to be transferring the value 

Here is a guide that can also help you accomplish this: https://www.jotform.com/help/270-How-to-Pass-a-Form-s-Calculated-Value-to-another-Form-s-Payment-Total-Field 

If you need more help, let us know what the first and second form is, so we can know from which form the total should be transferred to.

Can I do this with iframe on my website ? so it doesn't go to jotforms plain layout?

Unfortunately, this is only possible to pass through the form's direct links, it will not work between embedded forms.
