If formula with true/false check box options

I am building a spreadsheet to help my studios sell portraits and need a hand with a formula

I have attached the sheet so far

I am trying to have the last column give me a total of the qty with the options but if the qty is 0 then it does nothing

I thought i could do a =if(b15>0, then if f15=true or g15= true then b15*o8 or o9

Hmm?
1/. Why not use the Forum facilities to post a file?
2/. Why post a picture of a workbook you obviously have?
3/. Read the Forum rules and think about amending your thread title before the moderators get you ... ... , Forum rules can be found here Forum Rules, see Rule #1

You will find that people are unwilling to open files from unknown links, and are even less inclined to try replicating your workbook from a picture.
