Regards, Byron Hi Jary,

Here are some alternative methods to try:

$new_var =& $old_var;

or if passing through a function

function my_fun(& $old_var){
…
}

If those don’t work, post your code and I’ll take a look.

Regards,
Byron

Hadn't used it in such a long time I'd forgotten. As for the "@", it's used for operators and functions to tell PHP not report any errors if they should occur. A good example is if you want to delete a file - should that file not exist, PHP would return the error message saying that. Hah, thanks for reminding me about what the “&” does.
