Firstly, thank you both for all that input. Lots to think about and play with.

Luis Cazares - those two options are great, I think i can use those to achieve what i need and will have a play. Thank you.

pietlinden - those links are great, I can see how they too are going to help me achieve the end results, they go into great detail. Thank you for those.

I might well come back with more questions 🙂
