title: Blue prism "The collection has no current rows"
body: <p>In Blue Prism, after traversing the rows of collection using a loop, if any column is referenced to take first value of that column using CollectionName.ColmName, I am getting error saying "The collection has no current rows." although row count of collection is greater than 1. 
  How can I set the cursor back to the first row or any other way to get first value of a column? </p>
