Question : Critera Help for query in access if a field is null then ignore crireria

Hi EE
I have created a query which i use in a form to display records. I use the query as a filter.
In one of the fields on the query i want a criteria that is only used if the Unbound field on the form that the query is used for contains Text.

When you 1st open the form the unbound field is blank (field is a combo box)
I want the query to ignore the criteria at this stage as the combo is empty. this then returns all fields.
When you then select a name in the combo box it then uses after update event an Me.requery and now as the combobox has text in it the query now uses this.

I have tried the following:
IIf([Forms]![frmSUBResourcesTaskDayViewALL]![NameFilter]="","",[Forms]![frmSUBResourcesTaskDayViewALL]![NameFilter])

Also
IIf([Forms]![frmSUBResourcesTaskDayViewALL]![NameFilter] Is Null,"",[Forms]![frmSUBResourcesTaskDayViewALL]![NameFilter])

Both of these half work. If you select text in the combo box it works. It doesnt work if the combobox is null. it returns no records.

If the combobox is null or i delete the code in the criteria of the query then it should be finding 7 records.

assuming the field you are setting the filter criteria is [FieldX]


IIf([Forms]![frmSUBResourcesTaskDayViewALL]![NameFilter] Is Null,[FieldX],[Forms]![frmSUBResourcesTaskDayViewALL]![NameFilter])
