Be aware that object names (field, table, form, report, query, module) should only be letters and numbers, exception is the underscore(_).
Should NOT use spaces, special characters or punctuation.
Should not begin an object name with a number
Example:
Bad
Code:
Between [Forms]![Westwood Night Audit]![Start Date] And [Forms]![Westwood Night Audit]![CHQ#_Date].
Has spaces and the hash mark (# - the Date delimiter)
Better
Code:
Between [Forms]![WestwoodNightAudit]![StartDate] And [Forms]![WestwoodNightAudit]![CHQ_Date].
No spaces, no special characters...
