When setting up a block, you can specify on which pages it should display.
Best way to do this is to list node IDs in the 'Show block on specified pages' field.
Please note that node/ID must be in all lowercase, and not preceded by a /
For example:
node/1059
You can list multiple node/IDs on separate lines in the 'Show block on specified pages' field if If you need to have the block display on multiple pages.
