I am very weak with my grammar and apologize in advance for this stupid questions.
This is not verbatim the actual context, because it is relatively classified. However, I added new content that is really pointless in order to get my question across. I specifically am interested in the use of commas in this structured statement:
"According to the company's policy, the individual should ensure that the document is complete before the event, and when the event is in progress, have the office assistant complete form B101."
In my eyes, the "and when the event is in progress," is almost like an introductory statement following coordinating conjunction. I am unsure if the use of the commas is correct. I am well aware that the statement could be written better by including a period after "before the event"; However, I am unable to include a period in this statement due to rules that have been set forth by a higher power.
