Energy balance average data problem

hello , i am having a problem in creating a balance chart
when connecting the flrnormbalstorage output to the ladybug average data component it gives the run time error : attempt to divide by zero
is there any solution to this problem so i can get the balance chart?

i managed to create the energy balance , the problem was that i plugged a certain analysis period and didn’t calculated for the whole year

same issue can not be solved yet
