Instruction difficulties

The biggest issue I found while making an instructional booklet was consistency. One thing I need to work on with my booklet is consistent numbering as compared to what's in the table of contents. Most has to do with inconvenience of word and numbering. I changed my booklet so that the titles are all a, b, c in both table of contents and correct page but within each heading, the subheadings use i, ii, iii in the table of contents but when go to actual page they are 1, 2, 3. The 1, 2, 3 looks good and is easy to follow so its most likely something I will change in the table of contents. Everything just needs to flow a little better in mine. It is dificult to describe but this gets the gist of it accross. I thought pictures and screenshots would be good for mine, which they where, but I needed to limit them. There were too many pictures that were very close to eachother and didn't help the reader a whole lot or rather, they were't needed along with words. I limited the pictures and most are just what the screen should look like at starting points or to orient the reader in a given screen.
