Hi,
I am replacing my drop down control with a combo box to achieve the searching capability. I have below expression for items property on drop down control which works great and loads the values into a drop down control.
Sort(AddColumns(tblPersonnel,
"Fullname",
PersonnelFirstName & " " & PersonnelLastName
),Fullname,Ascending)
When I use the same formula mentioned above for items property of a combobox, I get to see below.

Can someone please help me modify the formula, thanks in advance.
