Using multiple Variables in conditional show

[#1]

Hi, I have two variables  "A" and "B".

In a conditional show on a graph, I would like both to be variables to be met in order for the graph to show.

What is the syntax for this?

I have tried the following wiithout success

A='Yes'& B='Blue'

Thanks

Ian

if(A='Yes' and B='Blue', 1, 0)

[#3 · Accepted solution]

A='Yes' and B='Blue'

that should work for you
