Error 3061 Too few parameters 2 expected

Error 3061 Too few parameters 2 expected

I have been facing the error 3061 with error message "Too few Parameters:
Expected 2". I have done all of the following to resolve the issue but
still couldn't it.
I ran the query in SQL mode and it gives me result
I checked all the field names
I checked all the "&" s are placed. I find them correct.
Here is my code:
Private Sub cmbYear_Change()
Dim db As Database
Dim rs As DAO.Recordset
Dim Query As String
Query = " SELECT Yrs_Teaching, Highest_Edu, AD_Descr FROM ClassSurvey" & _
" WHERE ClassSurvey.Program/School_ID = " & Me.cmbProgId.Value & _
" AND ClassSurvey.ClassID = " & Me.cmbClassId.Value & _
" AND ClassSurvey.Teacher_ID = " & Me.cmbTeacherID.Value & _
" AND ClassSurvey.SYear = " & Me.cmbYear.Value
Set db = CurrentDb
Set rs = db.OpenRecordset(Query)
If rs.RecordCount > 0 Then
Me.TB1 = rs!Yrs_Teaching
Me.TB2 = rs!Highest_Edu
Me.TB3 = rs!AD_Descr
Else
Me.TB1 = "N/A"
End If
Set rs = Nothing
Set db = Nothing
End Sub
I have been stuck with the same error for a while. Please help.
