title: Each Iteration of for loop value should be sum up outside the forloop
body: <p>I am just trying the below scenario in robot framework
  For Loop will run 2 times. Each time it will store a value in variable x
  Assume first run, it stored x=5 and in the second run x=2.
  Now i want sum of x in outside loop</p>
  <pre><code>For {i} IN RANGE 0    2
  ${x}=    Get Element Count    //tbody/tr
  LOG  ${x}
  Click Element    //tbody/tr`
  END
  </code></pre>
  <p>Both the iteration was successful, now i want to sum of X in outside loop</p>
