I have a form that is linked to a query which is able to update my ID field based on a text box. There is a chart in this form that then graphs this data. There are 3 fields of data that can be charted. I would like to have the option to turn some of these off and on from the form, preferably with radio buttons. I am unable to figure out the criteria necessary to toggle the "show" of a query field on and off. It is the equivalent of clicking the show checkbox in the query builder. What criteria do I need to type? Thankyou.
