2 zen cart modules need debugging

PLEASE ONLY APPLY IF FAMILIAR WITH ZEN CART, my last post had people assuming i was using woo commerce :s 2 modules i have created, both install but then give various errors, id love to claim all the credit for these delightful errors but sadly that ai bot coded them when promopted over a good few days, it seems to bat between being able to follow the task to forgetting elements that where mentioned too long ago for it to include into the code. I am looking for someone who can do this quite quick if possible. One module is for royal mail click and drop for Online Buisness Accounts (OBA) and the other is a qr tickets and admissions module add on that allows the customer to add a physical ticket to there basket. they are both stuck around the same are of a slight syntax issue in a file and no obvious resolution to me who cant code! i managed to get further along with items showing in the admin panel but dissapearing when i went to click the settings box. errors include such delights as.... [26-Jan-2023 14:40:47 UTC] PHP Fatal error: Uncaught Error: Call to undefined method royalmail_clickanddrop::keys() in /orDer-aMA-brIck/[login to view URL] Stack trace: #0 /orDer-aMA-brIck/[login to view URL](11): require() #1 {main} thrown in /orDer-aMA-brIck/[login to view URL] on line 201 [26-Jan-2023 14:40:47 UTC] Request URI: /orDer-aMA-brIck/[login to view URL], IP address: xxxxxx --> PHP Fatal error: Uncaught Error: Call to undefined method royalmail_clickanddrop::keys() in /orDer-aMA-brIck/[login to view URL] Stack trace: #0 /orDer-aMA-brIck/[login to view URL](11): require() #1 {main} thrown in /orDer-aMA-brIck/[login to view URL] on line 201. my favourite was when it said the language file was missing, noting i waited until id done all the files it suggested and it confirmed the module should work on both modules and its kind of just dropped straight in install wise just not functioning as expected but not causing an grey screens ect! I've shared the royal mail api module in its original form with all the required features and then the massively edited version most likely missing them features in certain files. maybe somebody here can after looking at the files decide they are up for what i hope to be a few hours work (it should be almost right right?) maybe to assume approx same time spent on both modules as a rough estimate if its not too far away. Hopefully the rars provided of the 2 examples help work out a timeframe for 2 modules made the same odd way Limited funds to get these modules done hence choosing to try and do it the way i did, seems the more i ask it to look the further away that it seems to indicate it originally was or was correct and has me delete good code ect. been at it for 2 weeks and i think its close enough to ask for someone to look at it for a small budget that is available to my home based business. I have no objections to the royal mail api module making its way to the zencart community contributions board and will be uploading it myself if the person who fixes the module into existence does not wish to take the honours of doing so :) The qr tickets module however i would like to keep as a private module for my use only and would require the person bidding to honour this. Files will therefore be provided for that module to successful applicant only after royal mail module fix and milestone payment. Apologies if you submitted a bid for my last job i posted, i accepted an offer and the gent never got back in touch with me. I am using the refunded payment as the initial downpayment for succesfull applicant. thankyou for taking the time to read my proposal, i hope it glances across the eyes of someone happy to help and curious to see what mess it made of the qr module! Im working on a subdomain as a test server running zencart 1.58. my store is somewhere between 1.57 and 1.58 just dont ask me where but if it works on zen 1.58 it should fit the bill as the upgrade is in progress slowly (i think)
