I have a combobox whose items are from a lookup field in a list.

Items:

Choices(SPList.Country)

I wanted to set a variable with a lookup() based on a combobox item since I'm going to use that for a switch case.

I tried doing

Set(_Country, LookUp(SPList, 'item' = _item, Country))

Set(_Country, LookUp(SPList, 'item' = _item, Country).Value)

but theres an error in the Switch function and_Country returns blank if i used UpdateContext.

Switch(_Country,
"USA",
Set(_rates, _usRate),
"EU",
Set(_rates, _euRate))

Any help or workarounds is appreciated.

Hi @rzainm

Try this

Set(_Country, LookUp(SPList, Country = _item).Country)

Switch(_Country,
"USA", Set(_rates, _usRate),
"EU", Set(_rates, _euRate)
)

Thanks!

Hi @Rajkumar_404

May I know why Country = _item in the Look up? _item is sort of like the item number.

The expression Country = _item in the LookUp function is used to find the record in the SharePoint list where the 'Country' field matches the selected item in the combobox.

if the combobox items are the names of countries, and the SharePoint list has a field called 'Country' that contains the same country names, the expression Country = _item will find the record in the SharePoint list where the 'Country' field matches the selected item in the combobox.

Thanks!

Hello @Rajkumar_404
I tried from
Set( _Status, LookUp( SPList, 'Entry No.' = _entry, Status ).Value )
to
Set( _Status, LookUp( SPList, Status = _entry ).Status )
It says these types can't be compared "Record" (which is the Status), "Number" (which is the _entry).

Country column in SPList is look up type to Countries list. Combo box items is Choices(SPList.Country).
'Entry No.' column is number type in SP List.
