Enabling a section

Am trying to enable some section with the following code

the variable an looking at is in the third roster for crop2 which is also in a roster plot2 which is in roster parcle2.
How best can i improve on the syntax such that i don’t get an error.
‘Roster Collection’ does not contain a definition for ‘plot2’ and no extension method ‘plot2’ accepting a first argument of type ‘Rosters Collection’ could be found (are you missing a using directive or an assembly reference?)


your code has a syntax error and the program correctly determined this.

If you explain what you wanted to check for then perhaps someone can suggest a proper expression for that.
