Re: Undefined index Error

As the error clearly states, on line 43 of your view code you are
trying to access an undefined index (variable or array).

Find line 43 (we're not going to do that for you as the block of code
is now poorly formatted due to Google Groups width restrictions) and
make sure you're setting the variable in the controller or remove the
varable if not needed.
