Why do I get Blockly errors when uploading the model?

Overview

When uploading a model that was recreated from an existing VC model, although the model loads, it will not build a Prototype. 

The reason for this is that when the upload sheet is recreated, all of the IF statements will have spaces added between variables. Even though Excel handles the extra spaces without an error, the Value Collaborator does not just like in the case of extra space/s added in any formula.

The solution to this problem is to remove all the extra spaces and then upload again.
