I've got myself in a real state with a simple assignment. I'm very very new to this and just when I thought I had got there of course I hadn't. I've been told that I need to allow the user to restart through every step in this ordering process. I found a way of using bool to allow the user to do this, but I'm thinking I must have messed up my loop because suddenly 'restart' isn't picked up any more. I know it will be something simple that I'm missing but can anyone help at all please?
Here's the code, apologies that I haven't neatened it up yet. I'm really really new to this and finding it very tough going so bear with me please and thanks in advance -
