Passing a variable from one sub to another sub

Please help me in passing one variable with value from commandbutton click event routine to optionbutton click event routine.

Your timely help will complete my project. Thank you in anticipation.

I'm just curious - are you trying to pass value of variable declared within commandbutton_click procedure to optionbutton_click procedure? I think this is impossible, because optionbutton_click procedure does not accept any variable byRef or byVal (but I may be wrong )
What I would do is to declare global variable (Public or Private) then assign it a value in cmd_click procedure and after that you can use it in optionbutton_click procedure.
Maybe some more experienced users will have better ideas.
