VBA code simply automates the Office applications, so it is imperative that you have a good grounding in how those applications work and how they are used.

As I have just realised that you are using macOS I am not going to be able to help you as I don't have access to a mac version of Word to guide you through the interface.

As it is for your job, do you have any co-workers with a better knowledge of Word that can guide you?
