Pass a variable between a controller

Thank you all for your replies.

The resaon I wanted it to be a link is that the entire process involves a lot of links, and I was worried about getting timed out, but maybe simply passing the data as a parameter is the best solution.

I think I am missing something...the code that I'm using in my original post

$this->csv_file

Is empty when I try to target it in parse_csv even though I am giving it a value in upload_csv...is this correct?

Thanks again,
Taff
