Transfer Variables from form to form

[sebastopol123]

Sorry all, this must be very old hat, but I'd appreciate some help.
I open a form and input data. I have the option to open form2 and with the OpenArgs transfer data. While I'm entering data I need to call form3 and select data from combo boxes. This is done without closing form2.
When I finish selecting from form3 I want to transfer the selected data back to form2 and close form3.
Many thanks

seb from form3 you can access objects in form2. For example you might want to populate a text box so you would simply do:

form2.txtWhateever.text = cboWhatever.text
