i want to use some variables in other variable
I've created two variables 'a and b' in variable overview
a = Sum(functionA)
b = Sum(functionB)
and when i create 'c'
c = $(a) + $(b)
the result is NULL
did i make a mistake?
Go to Solution.
whoops my bad
Forget use symbol '$' in my expression
seems you are ok
are 'a' or 'b' date dependent?
were 'a' and 'a' created in variables? and 'c' is defined in a graph?
The variable your definition most needed to reply. So, i would ask you to share screenshot of your variable definition..
