Here are a few things to look for:
1. APA Style applies to both your in-text citations and reference list, AND ALSO your paper's formatting.
2. If you are utilizing a source in your reference list there must be at least one in-text citation for that source. Similarly, if you have a source as an in-text citation it must be listed in the reference page.
