Help with Forms and Formula's

Can anyone recommend an Airtable Consultant, preferably in the UK, who can help me with some fairly simple formulas which for some reason, I cant work out why, are not working and/or producing missing data in some rows. I feel very scrooge-like and miserly saying this, but its the reality: I work for a charity so they cannot be too expensive. But I would be very grateful if somebody could help me. I have designed a multi-layered survey that evaluates the diffferent well-being dimensions of our clients and if I cant get it working soon I fear my project will be binned and I will be devastated as I've already done a lot of research and learnt airtable especially from scratch just do this- plus I love Airtable. So if somebody could help me that would be brilliant.
