Is it possible to use a Let variable to verify the value of a global variable?

Could this be done using a Let

$SelectedSearchColumn = first_name and $$first_name = "descending"

For example, can I do something like this?

("$" & ~varName) = "descending"

This is my attempt...which does not work.

Let ( [
    ~varName = "first_name"
    ] ;
    $SelectedSearchColumn = ~varName and ("$$" & ~varName) = "descending"
)

Not sure what you're trying to do here. What exactly does "verify the value of a global variable" mean?

 

 

 

Perhaps you meant something like =

Let ( [
varName = "first_name"
] ;
Evaluate ( "$$" & varName ) = "descending"
)

This would return true if a previously declared global variable named $$first_name exists and its value is "descending". Though why would this be preferable to simply =

$$first_name = "descending"

Sorry, I did not do a good job asking the question but you solved the problem for me.

 

This worked:

$SelectedSearchColumn = varName and Evaluate ( "$$" & varName ) = "descending"

Thanks!
