Can anyone tell me why:-
class=\"$this->styleclass\"
statement in the function generateHTML() (which is at very bottom) fails to
pass the value "error" meaning I can't use the style class I defined?
In the example below, I instantiate 3 objects and pass initial arguments to
the constructor. Before displaying the form, I wish to pass a new argument
to one of the objects. I tested it the syntax to ensure the assignment
statement was correct using a simple print statement to confirm it had
updated and indeed it had (this has been commented out below).
Cheers
Phil
