References styles how to change to numeric？

[Runli Liang]

Hello everyone, I have added references but instead of numbers in the main text, I get a summary like Reisingeret al.(2014) , how would I modify this so that the references are shown as numbers in the main text?

I believe the ASU template uses the natbib package. add a [numbers] command between \usepackage [numbers]{natbib} . I have included a snip of my document below.
