I need help linking items on my database

I have created a random question generator for chemistry. At the moment it works perfectly. Although my coding may be pretty messy. I can't work out how to now show the answers to each randomly generated question.
It would be best if I chatted to you on the phone to explain it. (That explanation sucks!)
If your keen let me know. I think the job would take an experienced coder no more than 10 minutes. I'm happy to pay for however long you think it would take. But then you would need to see the website etc. etc.
Let me know if you are keen and we can take it from there.
Many thanks,
Patch
