Hi again all, im getting the error below for this SQL statement in VB.Net

SQLString = "SELECT AllPropertyDetails.PropertyID, Street, Town, County, Acres, Quotas, ResidenceDetails, Status, HighestBid, AskingPrice FROM AllPropertyDetails "
    SQLString += "INNER JOIN Land ON AllPropertyDetails.PropertyID = Land.PropertyID "
    SQLString += "WHERE Deleted = False "
    If PriceRadioButton.Checked = True Then
        SQLString += "ORDER BY AskingPrice ASC"
    ElseIf AcresRadioButton.Checked = True Then
        SQLString += "ORDER BY Acres ASC"
    End If

Any ideas why its not working? The fields in the DB and the table names seem ok but its not working :/
