Run filter from button on subform

[tagteam]

I am using a split form with the worksheet on the left and on the right is a regular form on the right with the regular form is a subform using the type of form of continuous form. I am trying to create a button that will automatically filter the sub form, which is a continuous form, with prespecified conditions. however it does not seem to work I have tried a couple of different options including DoCmd.pplyFilter As well as formname.filter with where conditions.
I just want to be able to click a button on the sub form and have it filter for my preset criteria.

You did not say what that button will do or how you want the subform changed but maybe use the Record Source of the subform with specific criteria to manipulate it and at the end of your code on that button, do a Forms!Mainform!Subform.Requery (change Mainform and Subform to your names)

Ok, sorry sent the first one from my phone so didnt want to type much. Here is more detail.

I have a form that queries a table. I have used a split form so that on the right is the worksheet view of all the data in the table and if the click on a row it will load that individual record in the form on the right. So the right side is a regular form that displays the data in a more user friendly layout. On the right sid the top is where the data fields are from the table and beneath that is a subform that pulls records in from anther table. So we will call the main form the Cars form and the subform will be the communication table. In the subform I am using the form type: continuous form. So it shows all the communication we have had related to a car. One of the fields in the communication subform is called ComFlow. This tells us if it was a communication TO a customer of From a customer. I am trying to create a button on that subform that will filter the communications subform for only ComFlow = To ( and a different button for From). I will end up putting about 6 buttons just like these to filter the communications subform based on Whether it was To or From and what type of communication.
Thanks for any help

Maybe use Filter code in your button:

Me.Filter = "ComFlow = 'To'"
Me.FilterOn = True

Yes, perfect. Thank you. I tried several different variations that were like that but couldn't quite get the syntax. This one works great.
Thanks
