Creating Function to refer control in Subform

[mubi_masti]

I have a main form which contains two subforms;subform1 and subform1 and a button btn

subform2 also contains a subsubform.

i want to develop a function which will be called through a button btn available in main form

through this function i want to pass values to first the controls of subform2 and then controls of subsubform. This values will add new records in subform2 as well as subsubform.

Can anybody help to develop this function

Me.Parent.Subform_MDB.Form!MDB.locked = false
Me.Parent.Subform_MDB.Form!MDB.Value = 0
Me.Parent.Subform_MDB.Form!Subform_MD.Form.AllowAdditions = True
Me.Parent.Subform_MDB.Form!Subform_MD.Form!MDBAct1.Value = "1"
Me.Parent.Subform_MDB.Form!Subform_MD.Form!MDBAct2.Value = "1"
Me.Parent.Subform_MDB.Form!MDB.enabled = False
Me.Parent.Subform_MDB.Form!MDB.locked = True
Me.Parent.Subform_MDB.Form.Requery
