Script Error on Output0buffer - emailaddresstxt - why ?

[gsxrian99]

I have the following script and just want to pass same data thru the script.
I cant get the SSIS 'copy column" function to work and the output0buffer.emailout works fine.
Why does the output0buffer.emailaddresstxt not work ?
Thanks
