Solved how to only filter a field if its not null, if not null then filter the query (1 Viewer)

[Sodslaw]

I have a form that opens a query. In the query, there is a filter...
[Forms]![FrmNote]![AC_No]

Target objective
If in the form [AC_No] is null then show data for all CustomerID in the query
however if [AC_No] is not null then it displays the query for a specific CustomerID that is defined in the [Forms]![FrmNote]![AC_No]

to me, it sounds simple but I am having issues in making it work.
Any Ideas? thanks in advance

Show All Records if Form Control is Left Empty

How you can use a form to apply a filter to a query, and still return all the records if the user does not make any selection.

You may also find this Steve Bishop video useful. He shows the filtering technique around the 18:30 point in the video. He has many Ms Access videos on youtube.

No need for a like unless you want to search within a field?
To get all records when the control is NULL, just use that extra criteria for the form control being Null?
