Geoff, I'm not sure I follow what you say you are doing. What you need to do is have a global variable for the value you want to pass back from your Popup form, this global should not be used as a Field handle. Copy the value out of the field on the close of your popup form. In your frmUpdate event in your calling forms even handler take care of assigning the new value to the field on the current form and redrawing it. You should have save behind marked in your Popup form. Also you want to be using FrmReturnToForm not FrmGotoForm when you close your popup form.
