Hi Torsten,

So I have,

Also, any chance you know what else might be wrong with my coding? When I run it the following errors come up:

Wow, thanks so much for that... I can't believe it was that easy!

Hmm as much as I'd hate to admit it I think you're right.

Ok, So I've had a go at the explicit version and the results I'm getting are exactly the same as when I did my Excel model up which is good, however it is taking me forever to do and I'm not sure how I'd ever be able to graph it because of all my different u values. I'll show you my code, can you tell me if there's any way I can shorten this procedure so that I don't have to repeat and repeat and repeat. I think I need to do a for loop of some sort which I'm very rusty on. Anyway here's my code:
