Program not recognizing if statements
For some reason this program isn't recognizing the if statements I put in setPricePerYd...I can't figure out why that is. Any help would be great!

Tabs have no effect on if statements unlike other languages. You can only use it for one line without brackets.

Something else to watch out for is dangling else statement:

if <condition>
if <condition>
<expr>
else // this else belongs to the closest if statement, not as it appear in formatting
<expr>
