This is my Custom Function and I want to edit it

Hi,
I found that if the openbracket and closebracket are the same character then the function returns a single character...the bracket.

I changed the function such that the location of the close bracket is AFTER the location of the openbracket....

original: p2 = Position ( theText; closebracket ; 1; $instance ) ;
change: p2 = Position ( theText; closebracket ; p1+1 ; $instance ) ;

Now, i can find quoted strings with the function :)
