Prompt
Create a multi-level dependent dropdown system that dynamically updates based on previous selections, with built-in data validation and error handling. The solution should support up to 4 cascading levels, prevent invalid selections, and automatically reset lower-level dropdowns when an upper-level selection changes. Include a mechanism to pull data from a separate 'master' worksheet and implement conditional formatting to highlight potential selection conflicts.
