Firstly stop asking the same questions in two different threads please.
You said in this thread here that it was solved?
DLookup *returns* a value, most times by using some criteria.?
You cannot use a field element with spaces unless you surround the field in square brackets []
So if the contents of Me.cmbIndi can have spaces, enclose it in square brackets.
Try
Code:Me.LblData.Caption = DLookup("[" & Me.cmbIndi & "]", Me.cmbPub, "[Tahun]=" & Me.cmbTahun)
HTH
I’m so sorry for duplicate question in difference threads

I think it was solved but after I try it again there was an error.
I try your code but there are new error
Run-time error ‘3464’ it said
