Hi,

I am trying to apply lookup formula to my SharePoint list based on the Person Group field. I have New Form with People Picker card which i am populating with the logged in user. I need to prevent duplicate entries in the SharePoint list by using lookup formula but i am not getting any result.

Formula on submit button is given below.

If(
!IsBlank(
LookUp(
'EmployeeCoins',
Employee.DisplayName = DataCardValue5.SelectedItems.DisplayName
)
),
Notify(
"You have already claimed the bonus!",
NotificationType.Error
),
SubmitForm(BonusForm);
ResetForm(BonusForm)
)

Please Help.

Hi @AbdPower ,'

You need .Selected - note ID here can be any field in the list - I am just testing that it exists if using IsBlank

If( !IsBlank( LookUp( 'EmployeeCoins', Employee.DisplayName = DataCardValue5.Selected.DisplayName ).ID ), Notify( "You have already claimed the bonus!", NotificationType.Error ), SubmitForm(BonusForm); ResetForm(BonusForm) )
