Setting initial value for a Ref column from another table

[MAQ-381]

Hi,

I am getting this error while trying setting initial value for a Ref column on my AppSheet form.

"The expression is valid but its result type 'List' is not one of the expected types: Ref"

Tables: 

Banks: Bank Name, Default (Y,N)
Transactions: Date, Bank Name, Amount, .....

Banks table has multiple banks but only one is Default = Y at a time. When I open Transactions form, I want default bank to be selected automatically. Then user should have a choice to change the bank, if needed.

This query for setting initial value failed.

Select(Banks[Bank Name],([Default]="Y"),False)

Appreciate your help.

Issue solved by using this formula

LOOKUP("Y", "Banks", "Default", "Bank Name")

Another way is to wrap the formula with ANY() like as ANY(Select(Banks[Bank Name],[Default]=TRUE))
