Guided Access not working

Hi shelbz_m20

welcome to the Apple (user-to-user) Community!

Re: "Guided Access not working : so i've turned on guided access but it seems to not work password settings are on and everything i'm very confused i've put it on through settings and my action button but it's still not working how do i fix this?"

Guided Access limits your device to a single app and lets you control which features are available. You can turn on Guided Access when you let a child use your device, or when accidental gestures may distract you.

Seems you just need to start a session, and learn how to control what features are available, then end the session.

Apple Support have an article online that may help: How to: Use Guided Access - Apple Support

Eg: says:

"Start a Guided Access session

1. Open the app that you want. 
2. On an iPhone X or later, triple-click the side button. On an iPhone 8 or earlier, triple-click the Home button.
3. If you want parts of your screen to stop responding to touch, use one finger to circle those areas. You can move or resize the circle, or tap the X to remove it.
4. Tap Guided Access, then tap Start.

Or to start a Guided Access session with Siri*, open the app that you want, then tell Siri "Turn on Guided Access". 

(*Siri features may vary by country or region.)"

The article itself also explains how to: "Control which features are available" ... you can click the link above.

If you want to: "End a Guided Access session"

says:

"Triple-click the Side or Home button, enter your Guided Access passcode, then tap End.

Or if you turned on Touch ID or Face ID for Guided Access, double-click the Side or Home button"

All the best :-)
