How to allow decimal numbers input in forms?

I need to get in my form in one element a decimal number as an answer (reseller have to tell us their calculation factor which could be f.e. 1,98 or 2,25 or ...)

But when i use in the form the regular jotform-element "Zahl" (that is the german word for "number"), it is not possible to fill in a decimal number. only an integer, it is not possible to write a comma.

In the properties of this jotform-element there is no possibility, to change it and allow decimal numbers. and i don't find another jotform-element to make it possible.

what can i do?

Hello,

I can recommend to try Form Calculation widget. It should work the best for your needs. Please add the widget following this guide: How-to-Add-a-Widget-to-Your-Form
