Get Selected Count

[yashcena]

I have the following data in my data model.

A resource works for 40 hours in a week. My requirement is that when user selects n number of projects, then the corresponding projectedhours should be substracted from 40.

Ex: If user selects 2 ptA projects and 3 ptB projects then (2x2.5hrs)+(3*4hrs) should be subtracted from 40 and I should get 40-12=27.

If user selects 1ptA project and 2 ptC projects then (1x2.5hrs)+(2x3hrs) should be subtracted from 40 and I should get 40-8.5=41.5.

I hope I have made the requirement clear. I'm not able to use the projectedhours in the expression.

Thanks,

Yash

Is this not working

40 - Sum(ProjectHours)

EDIT: Why are you not able to use ProjectHours in your expression?
