[indiranell]

Steps to Reproduce -
1)Create a csv file(Hospinfo.csv)with the attached Hospinfo.txt
HospInfo.txt
2)Start the server: python run.py
3)Go to localhost:6464 in your browser
4)Input the zipcode '72042'
5)Click search

Expected - The generated output text is "DEWITT HOSPITAL & NURSING HOME, INC is within a mile away and does not have an available rating. Their listed phone number is 8709463571."

Actual - The generated output text is "DEWITT HOSPITAL & NURSING HOME, INC is 0.00 miles away and has 0 overall rating. Their listed phone number is 8709463571."

Issue - Since the hospital overall rating is 'Not Available', the reader of the text should be aware that no rating is available for that particular hospital instead of just saying '0 overall rating'
