I have the following problem, I need to build a graph that takes all 4XXError_Maximum and the total time analyzed and make a division as follows 4XXError_Maximum / total time analyzed, but as you can see in the images below when he performs the division he gets value of 0.800, it should not be that value, the correct value would be zero because there is no error as you can see, in this case I am analyzing the total time of 5 minutes, and the 4XXError_Maximum is 0, so the division should be zero.

note: I am using transformations to count the 4XXError_Maximum and total time analyzed, then I do the math
