JavaScript jQuery Basics (2014) Creating a Simple Drawing Application Perform: Part 2

Color sliders are not showing

After opening workspaces and previewing the initial code, the sliders dont show up when pressing the "new color" button. Anyone else has this issue?

Hey there,

revealColorSelect is an ID. You're missing a # :)

But of course! Haha! Thank you Andrew! Its awesome that a teacher who is on the actual video, takes time to help. I like Treehouse a lot.

Than you , Andrew, for taking a look.
