You can edit your posts. Please post code using code-tags and not plain text.
You posted the line but you seem to think it’s valid C# which it’s not. The line preceeding it is “if (rb.velocity.y > .1f)” so this line should likely be “<” rather than a comma and just looks like you’re copying code from somewhere and have mistyped. If that’s the case then all you really need to do is just look at the code you’re copying and check yours. 
Thanks.
