The core problem: Using the indirect function to set the validity of the next-level data, an error message appears
Solution: When setting the validity of the second-level "city", you must first select a value in the first cell under the first-level "province" (choose any one, it is not important) , will be deleted later)
Next step: Then just like the third step, use the indirect function to set the data validity. At this time, click "OK". No error message will appear
Finally: delete the cell where you just entered the value casually, set it up, and then you can enter the real data according to actual needs.
