You can't enter decimal numbers in the configurable list such "12."

You can enter decimal numbers in the configurable list - such 12.33. But when you use the Form Calculation widget it will not work unless the numbers do not contain decimals. Trying to use the configurable list for a reimbursement voucher that has dropdown of account, description and the amount requested. It will calculate only if numbers do not contain decimals. How can I make it recognize numbers with decimals?

Originally, configurable list widget can't be used in the conditional logic and calculation so what you're trying to achieve is not possible.
