How Can The Field On The Current Form Be Used As A Parameter For A Query?

Hi-

I have an Access DB with several different forms all relating to one master table.

Each record in the table can be resolved=yes or resolved=no.

Right now each user must click the resolved box to resolve the entry and then enter the date.

I have created a button that will run the update query below.

UPDATE [TBL Master] SET [TBL Master].[Resolved] = Yes, [TBL Master].[Date Completed] = Now()
WHERE ((([TBL Master].[Primary key])=[forms]![frm name]![primary key]))
WITH OWNERACCESS OPTION;

The query allows me to update the record on that form efficiently. However, I do not want to create one query for each form (30 plus) for this.

Is there a way to use the form that was used when the button was clicked without naming the form specifically?
