Hi Ross,
Happy to help!
I was able to fix your project file by changing the variable that your slider used from 'Dial 1' to 'Picture 1' which from my testing showed was the variable that was changing in value. I also changed the variable that your triggers were referencing to the correct one.
I noticed that the reason why the slider in your project file was not moving was because it was referencing Dial 1, which had a value that was not updating when the menu was rotated. To summarize, the main reason why the background image in your slide was not moving was because of incorrect referenced variables.
I have attached an edited version of your project file with the triggers and objects now referencing the correct variable.
Let me know if you have any questions!
