Form_Load event and use

[DDH]

I'm have a question on the correct way to use a Form_Load event. I have a frmMain that has rad buttons labeled 1 thru 4. I also have a class form that we can call CClass, and this form has set the text to these buttons as button one = dog, button two = cat, ect... My questions is how do you have the frmMain load the changed variables off of the CClass form as the frmMain loads up? Where and how do I put in the statement for these?
