Hi Ade,

I'm with goty on this one. The SS you describe is made up of very basic and simple Excel formulae, but sounds complex in structure; too complex to be designed over the internet.

As goty said "Excel is pretty easy to learn so have a go yourself but if you need help with specific formula questions then post them here and we'll try to help." I was similarly overawed at first, but found the going quite easy and pleasurable when I 'dipped a toe'. So much so that now I'm tackling quite heavy stuff.

I, too, will be around if you need assistance, so all I'll add is 'go for it!'
