On the Project Variables tab,
you can define project-wide global variables and variables that change
over the timeline of your project. You can reference these variables
in calculators that you create on the Calculator tab.
Procedure
- On the Project Variables tab, use
the command line or the + button to enter the
name, type, and value of the project-wide variable. You can define
complex project variables as you create complex calculations in the
calculator. For example:
numUsersProject = T(1000,1500,2000)
costPerUserProject = N(100,10)
costProject = numUsersProject * costPerUserProject
- To use any of these project-wide variables, on the Calculator tab
and within a calculator tape, refer to the names of the variables. For example:
numUsersLocal = T(300,350,400)
costPerUserLocal = N(50,2)
costLocal = numUsersLocal * costPerUserProject
costTotal = costLocal + costProject
Note: Within
a tape, if you define a local variable with the same name as a project
variable, the local variable masks the project variable.
