I have a product which has 3 sizes and 5 different attributes which are common, but the attribute prices changes depending on the selected size. ive tried the combinations tab and it seems to hold on to a single attribute price for all three size, how can i get around this. For Example Hot Dog Small = $10 Regular = $20 Large = $30 Attributes = Check Box Mustard For Small = $1 Mustard For Regular = $2 Mustard For Large = $3 So if i select a regular hot dog with extra mustard, it should be $22. But it holds it to $21. Please help
