Hello,
I previously used DropDown but I found out that it does not have an inline search. So I have to use a Combobox for this function. The snapshot is from the list populated by Combobox1. Multiple selection is off. And the items property is a SQL table called 'Details'. The list that is shown is from a Column/Field named Customer_Name in the 'Details' table.

Now the lookup query is not working to retrieve the Customer_Id from the same table 'Details'
LookUp(Details, Customer_Name = Combobox1.SelectedItems).Customer_Id
But if I use the code below, it successfully returns the Customer_Id
LookUp(Details, Customer_Name = "Understated advantage").Customer_Id
What am I doing wrong here? Any help is appreciated.
