What's missing with this Sass function.

Instructions are to write a function called double that multiplies the input by 2.

Hi, Andy. It's just being finicky; the challenge will pass if you remove the parentheses around your statement after @return.

Generally, it's ok, when it's not being particular, to have the parentheses?

Yep, those parentheses will work just fine outside of the challenge. I actually prefer parentheses because it makes things easier for me to read. :)

Ah! Sweet, thank you! I was getting very frustrated. :)

FWIW, In general you should follow proper "tail practices" that'll lead to minimal use cases of needing to surround any expression within a statement with parentheses to be evaluated before a function returns a value.

return keyword likely couldn't be tokenized (understood) by the parser since you didn't have a space after return

This is where I get extremely frustrated with treehouse, thankfully the community is excellent but I was working on this function for 20 minutes only to find out it was a parenthesis problem that was technically correct.
