Hi, I've been using excel for a while but have been self taught, so I don't know all the lingo and in's and out's. I'm having a big problem creating a formula that's based on other formulae. Please help! I've tested each formula on their own, and they work, but I now want to add each formula together to make a total sum and it's not working. I keep getting the #VALUE! message, but it's not telling me what to change. There are a lot of brackets, etc, but I can't figure out what I'm doing wrong! Is there anybody who can help me? Do I have to type the formulae in this message to get help?
