Using calculated label in expression

[#1]

Hello all,

Can somebody help me with this. I now it's out there, but i can't find the answer anywhere.

I want to use an expression in an other expression. Now i know i can do this by using the label of the first expression in the second. But what if the label of my expression is calculated (lets say my expression has the label "=count(TaskID)") how can i use this expression in an other expression?

Hi tom,

u can put this expression in variable and use any where,any time u want.

let v1=count(TaskID)

now example usage in some expression say to increment:

=$(v1)+1

I think the answer is to use Column(n) in place of the column label.

and where can i see the column nr?

[jonathandienst]

It is the expression number (counting from the top) in the Properties | Expresssions tab. Starting with 1.

in column label give ColumnNo
use "ColumnNo" in any expression  uwant.

else in a chart say u have 2 expressions; 1st expression is always column(1),2nd always column(2)...so, in 2 nd expression type"=column(1)+any calculation u wanna make" .
