  </blockquote>
  
  <p>For eg: I want the output to look like this </p>
  
  <pre><code>Col1  |Col2  |Col3  |Col4(Calculated Col) 
  12    |16    |10    |38 
  1     |5     |2     |8  
  </code></pre>
  
  <p>All I am doing is selecting the column titles Col1, Col2, Col3 then right click and add calculation. It gives only one option that is to concatenate and the result is </p>
  
  <pre><code>Col1  |Col2  |Col3 |Col4 
  12    |16    |10   |121610 
  1     |5     |2    |152 
  </code></pre>
  
  <p>This is not what I want. Can anyone guide? 
  Pls note: I also used a cast function to change the datatype to integer just to be on a safer side. </p>
  
  <p>Thank you in advance </p>
