Hi. I have one listBox for startTimes and one listBox for endTimes in the format: "yyyymmddTHHmmss".
I am using the "mid()" Expression function to only retrieve the hours, "HH" from this string and show the total hours in a Chart.
But it seems like I do something wrong because the result of the chart should be:
15-13 + 15-13 = 4
But of some reason it shows the result as 48. Any ideas why?
Attached the listboxes and chart.
