Please check definition and inputs. Interface Definition: Expression evaluation error at function a!gridField [line 5]: A grid component [label="Read-only Grid"] has an invalid value for "columns". A grid column [label="A Id"] has encountered an error. Expression evaluation error: RTA Customer Data can only be indexed into using square brackets or the index function"Can someone please help me how to solve this?

Could you please share any snapshots of the code as well?
This is the query code which I am trying to use in a read only grid. In read only grid, after specifying the rule to be used, the above error pops up. The purpose is to use two filters at the same time in read only grid using expression rule.
in your values can you something like fv.row[ recordType!custmerData.profession]
fv.row[ recordType! custmerData.accounttype]
make sure in your expression query rule you have fields profession and accounttype
Please use your value statement of grid-column like the below
Thanks. It worked perfectly after adding fv!row.
That's Great
