Trying to make a volume slider

I Need help I Tried To Use A Global Variable To control my Sound And it did not work what do i do

In those events you are setting the value of the slider to the value of itself. You are not setting any variable.

sorry posted the wrong snapshot i believe this is correct

Ok, and what about the events where that set the volume levels?

I made this a simple volume changing event including the save and load system too. Please notify if this helps.
Your welcome!!!

no it did not work ever time i press the accept button then go to the game the press start then press options it dose not save

Yo there
