How can I create multiple input fields within the same line with comma as the separator?

Hi

I'd like to order two number boxes (I know  to do that), but I like to separate them with comma like: first box for integer then comma and second for decimal number? the general sence is that I can do this easily with format in text box, but it doesn't allow to add a limit (like from 1,0 to 9,9). Then I thought dividing into two boxes is the best but how to add the comma between? (I tried to add the static text field "," but it doesn't look nice). Thanks in advance

You can use our Fixed Format widget for this: http://widgets.jotform.com/widget/fixed_format. Here's our guide on how to add a widget in your form:

But how to add limit range? I tried with logic condition but then it is set for both boxes 

How about using input mask? You can define there how many digits you want and then add a delimiter like comma. This is applicable if you want a fixed amount of digits.

Example:

Here's how it would look like in the preview:
