move one record from one subform to another subform

Using With operator u can access record of any form from any form. E.g.

If Form1 contains

txtName
txtAge

and u want to fetch data from Form2 then following action u can perform

in form2 load or any event where u want to call data write following code

with Form1
Dim name as string= .txtName.Text
Dim Age as string=.txtAge.text
end with

i guess this is what you were asking.
