## Output

A list of every available reward in a single rewards category. Output is also stored in a single-dimensional array, *$rewards*.

## Notes

Another template function, [nats\_display\_reward\_purchases](https://docs.toomuchmedia.com/nats-admin/skins-and-templates/further-reading/template-functions/nats_display_reward_purchases), also uses the array *$rewards*. If you call both [nats\_display\_reward\_purchases ](https://docs.toomuchmedia.com/nats-admin/skins-and-templates/further-reading/template-functions/nats_display_reward_purchases)and [nats\_display\_reward\_category ](https://docs.toomuchmedia.com/nats-admin/skins-and-templates/further-reading/template-functions/nats_display_reward_category)in the same template, the array *$rewards* will contain the output of **the last function run above it in the template.**
