Hi again!
I am indeed stuck on this again. I think it has to be close, but I don't know where my problem is. I get this error message: "Error 3061: Too few parameters. Expected 1."
Below I have copied:
- Query SQL code
- Control box expression for 'Fuel Type'
- Allen Browne coding for the function
Thanks for any help on getting past this error,
Julie
The SQL from the query is below, I get the appropriate result set from this:
SELECT EmissionsSCC_Asset.AssetID, EmissionsFuelType.FuelTypeDescription, EmissionsSCC.EmissionsFuelTypeID, EmissionsSCC_Asset.AssetTypeID
FROM EmissionsFuelType INNER JOIN (EmissionsSCC LEFT JOIN EmissionsSCC_Asset ON EmissionsSCC.EmissionsSCC_ID = EmissionsSCC_Asset.EmissionsSCC_ID) ON EmissionsFuelType.EmissionsFuelTypeID = EmissionsSCC.EmissionsFuelTypeID;
The expression for the 'FuelTypes' control is:
=ConcatRelated([AssetID],"Qry_Load_Fuels_part2")
The AllenBrowne module text is:
Public Function ConcatRelated(strField As String, _
strTable As String, _
Optional strWhere As String, _
Optional strOrderBy As String, _
Optional strSeparator = ", ") As Variant

'Purpose: Generate a concatenated string of related records.
'Return: String variant, or Null if no matches.
'Arguments: strField = name of field to get results from and concatenate.
' strTable = name of a table or query.
' strWhere = WHERE clause to choose the right values.
' strOrderBy = ORDER BY clause, for sorting the values.
' strSeparator = characters to use between the concatenated values.
'Notes: 1. Use square brackets around field/table names with spaces or odd characters.
' 2. strField can be a Multi-valued field (A2007 and later), but strOrderBy cannot.
' 3. Nulls are omitted, zero-length strings (ZLSs) are returned as ZLSs.
