Error:Error in expression: Len takes 1 parameter

[#1]

Hi all,

I am new to Qlikview and my current project is my first try at developing applications in Qlikview. I am trying to find length of variables and if the length is greater than '0' then show a particular expression in graph. However, when I try to use this len() function I get the following error:

"Error: Error in expression: Len takes 1 parameter"

Could anyone please explain this behavior?

Thanks in Advance!

You should actually show an example of your expression used to help us understanding the issue.

I assume you are expanding the variable, and it expands to something having commas, and you do this without encapsulation in single quotes:

vVar = 1, 2, 3

then don't do

=Len( $(vVar) )

instead

=Len( '$(vVar)' )

or maybe only

=Len( vVar )

What exactly is your expression?
