Goal Seek using Time
Hi-
I am doing a project that I am having difficulty with. Hope you can help. I am trying to use goal seek to see with the fourth quarter target needs to be in order to meet a yearly goal. The measurement is average time on a call. So the data looks like: Q1 - 00:03:52 Q2 - 00:05:25 Q3 - 00:04:18 Q4 - Average needs to be 00:04:30 for all four quarters to hit target. So I need the output to be a time in the Q4 cell. in the average cell, I used a formula to get the average of all 4 quarters. I used goal seek with the set value being the average cell, the to value being 00:04:30 and by changing cell is the empty Q4 cell. When I press ok, the goal seek status box appears and the target value has changed to 0.003125, and current value is 0:03:24. A 0 appears in the Q4 cell. I was expecting the Q4 cell to have a format of hh:mm:ss and it very well should be greater than zero. And the average should be 00:04:30 not 00:03:24. What am I doing wrong and how can I fix it? I already tried to convert to seconds, that wasn't quite working either. HELP! Thanks! |

You need to format the number 0.003125 which represents a fraction of a day.
If A1 = 0.003125 In spreadsheet =Text(A1,"hh:mm:ss") In VBA MyTime = 0.003125 TextTime = format(MyTime,"hh:mm:ss") "laya1024" wrote: Hi- I am doing a project that I am having difficulty with.

Goal Seek using Time
First I also got the same result as you.
Then I started with a new shee, formtted col A as Cutsom-h:mm:ss, entered the values you have given and got the right answer - 4:25:00 in cell B4... btw 0.003125 translates to 1/0/1900 12:04:30 AM... As you probably know Excel stores dates as a number with 1 being 1-Jan-1900 so when you enter 03:52 in a cell you are actually entering 1/0/1900 12:03:52 AM "laya1024" wrote: Hi- I am doing a project that I am having difficulty with.
