APEX Report Print header setting

For the report printing page setup, it said for the report header, we can use &ITEM_NAME. syntax  to show application or page item value.

However I put the page item name like &P5_NEW. in the heade area, it is now printed out?

We print it out as excel file.

Do you know how to use this syntax?

In fact, what I want to do is to print the report title and the sysdate in the print header.

If anyone know how to do this in other ways, that's even better.

Thank you.
