Expression Assistant referring incorrect column names

[Arinjay]

While creating a Show_if Constraint it shows error - has an invalid Show_If constraint. Unable to find column.

However, the slice that I am using has those columns. For some reason, the Expression Assistant is referring to columns from another table.

What do you mean?

A show_if expression on a Deck view cannot evaluate in the context of any single record, as a Deck view shows many records. Perhaps you meant to use that expression in your Slice’s Row Filter Condition?
