Please Help Me Test! (Patreon)

Hi everyone!  I'm working on getting the ear muffs ready for all ages, but I am having a super hard time using the sliders.  I know the toddler ones work with them, I just can't seem to figure out where to click?  I couldn't find it for the adults or kids at all, so, please help me!  Here is where you can get the sliders:

I attached the files, please let me know if you can get them working with sliders, feel free to post a pic!  They don't have a custom thumbnail yet, found in hats.  Thank you!
