Hi @Brandi Sumner,
Can you access the internet OK from your phone?
If not ensure that the “data connection” setting is enabled.
Do you have enough “storage'“ available in the phone to allow for the download?
If you can access the internet OK and assuming that you’ve cleared the Data and Cache areas from the Play Store app as per the link above, try updating the Play Store app and check if this resolves the problem.
To update the app, open the app, then tap ''Settings > Play Store Version''. If there is an update available follow the prompts to update the app and try again
