I am sure that this should be simple but after some time looking at it I cannot see what is wrong !
I have set up a tabbed frame and using the –caption option given it a ‘title’.
I then try to:
1. Retrieve this but nothing is returned;
2. Reset it using configure but get the message that –caption is not an option.
Can someone give me a clue as to why this is wrong.
The Perl and full output is given below.
