This page will help you to fix the cite error message:

The <ref> tag name cannot be a simple integer (see the help page).

• If you have read this help page and find something missing or confusing, please discuss it at the main talk page.
• Please reference this page and the page where you have the problem so we can understand your issues.
• For basic information on the footnotes system, see Referencing for beginners; for advanced help, see Footnotes.

A footnote used multiple times may be defined with a name:

<ref name="foo">content</ref>

The name of the reference may not be an integer. Rename the reference to contain at least one letter. It is a good practice to give references meaningful names. Ensure that when changing the name you update all the tags that refer to that reference.

Reference 1 is improperly named as 1:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.<ref name="1">Reference 1</ref> Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.<ref>Reference 2</ref> Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.
