**Boris**Hello Tom.

I see the issue, and it is much worse (calculation wise) than just multiplying it by 10. It is caused by conditions that you are using to update the total field - it loops on itself 10 times. The conditions to Update a form field value are not intended for a field to update its own value, based on its own value - there are many kind of unpredictable results.

As an example, if you tick the first checkbox (150USD), then tick the second one, and un-tick the second one, your total calculates to a whooping 43300.00 USD. :)

To fix this, you should first remove the Conditions that are updating the total field, based on the value of the total field.

Then, you need to use a Calculation field to perform your calculations. You can also hide it, just as you did with the Total field.

After that, you can set up Calculation value directly to your product options:

And finally, all you need to do is forward the calculation value to your Payment Tool.

Here is a demo that you can look at (note that I haven't hidden the Calculation field, so that you can see it in action):

Please let us know, Tom, if you need further assistance.
