Enhance JavaScript Calculator

I need an enhancement of the attached html/javascript calculator.

How it should work you can see in the attached xlsx file.

The calculation of the major part "Heizkosten" already works great.

Small changes to do:

1. The new fields, in xlsx file it is field I4 and I38, should be applied in the calculation.

2. Make the sliders work in both directions - number input should move the silder to the correct position.

New things to do:

3. Make chart like in xlsx file using flotchart ([url removed, login to view]) for "Heizkostenvergleich: Gesamtkosten / Jahr" and make Checkboxes like [url removed, login to view]

4. Make chart like in xlsx file using flotchart for "Amortisationsrechnung" with 10 and 20 (years) and make Checkboxes like [url removed, login to view] and Cursor like [url removed, login to view]

all charts must update as you type

Everywhere German number format
