Trouble comparing number values in formula field

Okay, so at the moment I think it seems to be working. Not 100% sure what the problem was but I deleted all formulas and re-wrote everything. The only thing that might have thrown it last time is I'm not sure if I was rounding the Quantity field to .01 which I am doing now so that its not 5x$2.99, it is 5.00 x $2.99. Don't know why this would matter since I was already rounding both numbers in the final check?? 

If it throws any more errors I will try converting to text. Thanks for your help!
