I've recently finished a course in smart contract and am trying to expand on the current project. One thing I'm trying to do is give more info into each campaign - things like, description, category, etc. I've modified my smart contract, but am running into an error, if you can help me take a look and point me towards the right direction, that'd be really appreciated! Also, if you can just take a look overall how I've modified the contracts to see if I have any redundancy anywhere, that'd be awesome. Cheers.
the error i'm getting on line 50 is - TypeError: Member "manager" not found or not visible after argument-dependent lookup in struct Campaign.NewCampaignType storage ref[] storage ref
