    Hi @Anonymous 

    I suspect that EmpID is formatted in your Table as Text (both the left alignment and the error you are getting would suggest this). Try the formula without Value()

    @Anonymous ,

    It is saying it will not accept a blank search box - you can try this

    If(
     Len(DataCardValue6_l.Text) > 0,
     LookUp(
     Employee_T,
     EmpID = DataCardValue6_l.Text
     ).PersonnelNumber,
     ""
    )

    however Excel is a terrible data source and that is another one that works for everything else that I have not seen posted before. I suggest you switch to SharePoint Lists if you have that available.

    I am having a similar issue. I have replaced my formula with the one you provided but I am still facing the "eq null" issue. 
    My changed formula: 
    If(
    Goal_Id_DataCard1 > 0,
    LookUp(
    Table1,
    Goal_Id = Goal_Id_DataCard1
    ).Goal_Id,
    ""
    )
