Aw, sad AA. She asked me a question about a formula in Excel. I pointed out two errors with it. One being a simple matter of dividing by the wrong line. Then I had to show her how Excel does not store time passed in a format of mm:ss and that when she tried to record 6 minutes and 15 seconds, Excel actually calculates it as 0.26, which totally throws their numbers out of whack.
What's sad is that this report has apparently been in use for a long while. The problem didn't come to light until someone tried to input 24:02, which Excel does not recognize as a legitimate time value. Now she's aware of just how flawed the report is. I bear bad news from Excelland.
