title: Reading specific fields from a CSV file
body: <p>I am trying to read contents of a CSV file but I get NAN for some 'reviewtext' field. 
  I have attached my csv file. When data.head() reads all values from the file but when I try to read only specific fields with revs.head() , it gives me an error.

  <pre><code> import pandas as pd
   data = pd.read_csv('Review_50.csv',sep='|',error_bad_lines=False)
   print data.head()
   revs = data.loc[:,['r_name','reviewtext','date']]
   print revs.head()`
  </code></pre>
