Oh I didn't know it was as complicated as that, but then I'm only a thicko, I suppose that's what the formula below means then. I could get good at this stuff if that's what it's all about. It's quite simple really, you just stick with the C for chilli, then we have to change the a to p for pitta bread, then the use the d represent donner meat and use the x to represent the salad. I'm sure it will work.......
