Error-91 VB script error

I keep getting error91 come up when I run my code which says that the object variable is not set.
It highlights the line:
'If OptionButton3.Value Then' when I try the debugger. I don't understand where its going wrong and I don't know what an object variable is? Has anyone else had this issue?

Any help would be much appreciated. Thank you
