Advanced Sass: Introspection Code Challenge

Running into an issue with this particular question, its asking me to complete the function using the 'comparable' function, but when I do I get an error that asks me to return a value ONLY IF something is true.

I've set up a if/else directive that should work but isn't. Have no clue why.

This one took me a while as well. I guess I never caught where he uses the comparable function so I kept trying to use "@if type-of($alpha)==type-of($bravo)" which always resulted in true since they are both numbers. Problem is Sass will not allow you to add pixels and % which is why you need to use the comparable function. The comparable function is built into Sass just like lighten and darken colors.

@function add-if-comparable($alpha, $bravo) { @if comparable($alpha,$bravo) { @return $alpha+$bravo; } @else { @return 'error'; } }

I know this is the same code, but it's a little easier to understand, thanks Nathan!

@function add-if-comparable($alpha, $bravo) { 
  @if comparable($alpha,$bravo) { 
    @return $alpha+$bravo; 
  } @else { 
       @return 'error'; 
     } 
}
