Okay, so create all of your buttons. The buttons that are on Panel2 should have their property .enabled set to false

When you press a button on Panel1, you can use the code that I provided earlier to change the property to true.

On your Panel1 Buttons for the .click event you need to pass the string of what buttons you want to enable.

For example
 Code:
$panel1_Button1.click = "EnableButton(Panel2_Button1)"
$panel1_Button2.click = "EnableButton(Panel2_Button1~Panel2_Button2)"
$panel1_Button3.click = "EnableButton(Panel2_Button1~Panel2_Button2~Panel2_Button3)"


Of course this does not just plug and play, you have to change it to work with your code.
