added affecting attempted blank checked collars colors cost detailed dog exact examle format gone help instructions jilmarie lines medium offer offered offering option options page price prices pricing size sizes variable varient

Hello, I'm offering dog collars with different sizes being offered at different prices. I've gone through and checked the varient affecting pricing box but don't seem to understand the exact format I need to place a price for 1)small 2)large 3)medium. I'd then like to use the variable options for each size to offer different colors which will not affect price. Need help with detailed instructions and or examle please as the help page just didn't work for me. I attempted to place size in the option 1 but then added cost on 3 lines and it just came up blank.
Please help :)
