Hi Tom,

I added two new lists at the projViewEfforts.

Furthermore I had to add two new functions to calculate the effort sum.

First I had only one function to calculate the effort sum per person or per task. And I took yout function to get the effort sum of the whole project.
But in this case I hade some discrepancy when I calculated the percentage (like 49,1% and 51,3% > 100%).

Therefore I created my own function to get the effort sum (directly from database).
I think the discrepany has something to do with your usage of the strToGMTime function.

There are also some discrepany because of truncation but they are very little.

The rest should be okay :).

Have a nice weekend.
