Paypal Error: OrderTotal (Amt): Required parameter missing OR "Bad Math" error

Issue:

Sometimes,  Paypal Error: OrderTotal (Amt): Required parameter missing or "Bad Math" error appear on the checkout screen, whenever FormBuilder has multiple checkboxes with identical words.

Example screenshots:

Solution:

The workaround is to change the multiple-checkbox options so that no option is identical to a portion of another option.

Also, it is recommended NOT to use the ampersand (&) sign since it also causes the issue at checkout.

& sing should be replaced with "and" word.

Please see an example screenshot of the previous case: (multiple checkboxes after correction)

In addition, it is possible "to use a separate multiple checkboxes element for the separate options." 

In other words, if multiple checkbox options contain a text of a later one, the user will need to move them to a separate element, so it should resolve the issue as well.
