As I understand your question, you know how to do the reference page entry for Zora Neale Hurston's short story "Sweat" but you're not sure how to do the in-text citations.
I recommend the source below (the two links to OWL at Purdue) for examples of what are called "in-text citations." The correct citation format, of course, will depend entirely on which citation style you are using. I would generally expect you to be using MLA format, but your term "reference page" (rather than "works cited") makes me suspect that you might be working in APA format.
In any case, be sure that you use the correct style (e.g. MLA or APA), as dictated by the assignment.
If this answer doesn't help, please post again and give a sample paragraph from your essay, one that uses a quotation from the story. Someone here will surely be able to tell you if the format for the in-text citation is correct.
