problem getting decimal not to = 0
Ok here is my program
Code:

Here is the output

444 15 500 500 7500 7500 0
445 20 500 500 10000 10000 0
Are there any more items to process? (Y/N): n
Total sales: 81850
Total Cost: 81850
Total profit: 0
Average profit: 0
Total tax: 0
High profit: 0
High item code: 0
Now as you can see, I am having trouble getting the correct output.
I narrowed it down and determined that it is all happening because profrate is pretty much = 0.
I input it correctly when I run the program (is supposed to be .2) but I can't figure out why it doesn't take. In the output it keeps acting like 0.
We are re visiting this program (for school), and the first time I did it I couldn't get it to work either. I ended up hardcoding in profrate =.2. That won't work this time however because the assignment requires that it be from input.
Please help, why won't profrate take the .2 value?
