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

Thank you for the reply. I've tried your suggestion and I must be missing something.
In form1 I have a text box and a command button. The button click procedure opens form 2. On form2 there is a text box and a button that closes the form2. This returns me to form1. I now want to enter into form 1 text box the contents I entered into the text box on form2.
All works well but I cant transfer the variable when I get back to form1.
Where do I enter the Forms!formname!controlname? When I used this in form1 I get an error.
Any examples greatly appreciated.
