This must sound so stupid but I have real problems trying to find the Instance Name text box in the Properties panel when creating a button symbol. I can see where it should appear but it says ‘Frame Label’…
Could anyone point me in the right direction?
You have the entire frame selected, click on the button 
Thanks for the reply…
Have tried clicking everything…no luck. I get the box if I do Modify> Convert To symbol but I can’t convert a button to a button. Pulling my hair out…
