title: Blue prism code stage for extracting collection data
body: <p>I have collection which gets populated during execution and hence has no Fields declared. I need to extract the values of last column, and number of columns is dynamic, and am not able to do so. How can I do this with or without using code stage? (Code: VB only, as I have other code blocks running VB)</p>
  
  <p>I have tried to replace the value with another variable in calculation stage like this: [my_collection.[column_name]]. It's throwing an Error when I press on Validate expression.</p>
