Expressions with variables

[#1]

Hi, I am new with QlikView and have a problem using variables:

I have defined the following variables:

v1:

sum({$<[Type]={'Apples'}>} [Total value])+

sum({$<[Type]={'Oranges'}>} [Total value])

v2:

COUNT(DISTINCT {$<[Invoice]={'Main'}>}InvoiceMonth)

I have uploaded the 3 different invoices with the values of the Apples and Oranges

v1: Gives me the total cost of Apples and Oranges.

v2: Gives me the number of invoices I have loaded.

I need to get the average cost and then extrapolate it for the whole year. I have defined the valariables as I have diferent types of invoices and that have been uploaded in different periods.

When I include in a table the following expressoins:

Ex1 =$(v1)  and I get the correct sum: 992.19

Ex2 =$(v2) and I get the correct number of invoices: 3

Then in a new expression I add:

=($(v1)/$(v2))*12

And the result is 5424.44 which is incorrect as (992.19/3)*12 = 3968.76

If I use the names of the expressions Ex1 and Ex2 it works fine, but I want to use the variables as the expressions are only there for testing!

Can someone help me with this?

Thanks a lot!

try with Column() function, like:

(Column(1)/Column(2))*12

Or, in your case

(Ex1/Ex2)*12

Hi

Try like this

v3 = $(v1)/$(v2)

Ex3 =$(v3)*12

Hope it helps

Thanks, This worked fine, but still can not understand why a new variable is needed!

Thanks again
