It compiles fine though after checking my checkbox it doesn't do anything. With this setup it'l only do as I want it to when I click on the actual label... I've tried using this on Form1_Load but it has no effect. Any ideas?
You're not really explaining what you want it to do, this also seems to be the third thread you made for the same question.
What you want is the event for when checkbox2's state is changed. The event listener it looks like you have there is for when label3 is being clicked. Create a new event listener for when checkbox2's state is changed.
