What this means??

Hi There,
I Have a problem with Shared variables. I took Crystal Report Help but didnt understand this sentence. What exactly does it mean??
-----------
In order to use shared variables the variable must be declared and assigned a value before it can be passed between the main report and the subreport. If this is not done, a blank or zero value will be returned with the variable.

That means you have to create a variable, and set it to a value before calling your report. Something along the lines of

VB Code:

Dim MyValue As Integer
MyValue = 20
'run your report
