Form Calculation: Section calculation in percentage

I need help with this widget. My form (https://form.jotform.com/82435962995170) needs to calculate the results of scores in various sections, and the weighted results. I am able to calculate the numerical scores in each section with simple addition. I can't figure out how to calculate the weighted scores for each section.

For example, if a section total score has a weight of 15% the calculation for the section score would be:

Section Score/Max Possible Section Score x 100 x 15% = Weighted Section Score

How can I make this calculation in the section total field?

Thank you for your reply on the help guide. Your question has been added to our forum and will be answered shortly.

I verified the calculation you are using in the section's WEIGHTED SCORE field. It appears to be working fine. 

For example below calculation, this correctly calculates the 15% score.
