Associate Zoho Project with Deal that is in a specific stage?

Hi there,

When a deal hits a certain stage, I'd like to associate it with an pre-exisiting zoho project? I am using blueprints.

Using a custom function and deluge, how could I do this? I was thinking that the easiest option would be the modify the pre-made custom function available in the CRM but don't know how?

Kind regards

Sarah
