Pass an object reference (thisform) into the replace form, providing a reference to the main form. Save it in a form property. When you want to update the control on the main form, reference it using the saved reference:

eg:

Create a property of form replace called oMainForm

In the Init of Replace:

LPARAMETERS toParentObject
this.oMainForm = toParentObject

when you want to update the control on the main form:

thisform.oMainform.edit2.value = whatever you want it to be
