Thanks for the advise, I have added the button and sub form's etc I was just trying to be very clear on the end result:
I added the following to the click event:
Code:
Me.frmSubStatementLastDate.Forms.MaxOfStatDate = MaxOfStatDate
I got the error message Compile Error Method or data member not found at the .Forms
Since original I have put subform1 =[frmSubStatementLast Date] which contains txtBox [MaxOfStatDate] onto the subform2 = [frmSubTransactionBalance] and I would like to place [MaxOfStatDate] into text box [trStatDate] on clicking the button
