I have a problem with my output when I input these numbers :

0
200
-1
12
y
-0.01
5.99

This is my output which is incorrect because it has those spacing's:

Spools to be ordered
Spools order must be 1 or more
Spools to be ordered
Spools in stock
Spools in stock must be 0 or more

Spools in stock
Special shipping and handling (y or n)
Shipping and handling amount
The spool shipping and handling charge must be 0.0 or more

Shipping and handling amount
Spools ready to ship: 12
Spools on back-order: 188
Subtotal ready to ship: $   1200.00
Shipping and handling:  $     71.88
Total shipping charges: $   1271.88


**Below is what the output should look like:

Spools to be ordered
Spools order must be 1 or more
Spools to be ordered
Spools in stock
Spools in stock must be 0 or more
Spools in stock
Special shipping and handling (y or n)
Shipping and handling amount
The spool shipping and handling charge must be 0.0 or more
Shipping and handling amount
Spools ready to ship: 12
Spools on back-order: 188
Subtotal ready to ship: $   1200.00
Shipping and handling:  $     71.88
Total shipping charges: $   1271.88
