I have followed all the given instructions in https://trailhead.salesforce.com/content/learn/projects/analytics_charts_icons/analytics_charts_icons_gauge?trail_id=wave_analytics_enable_and_produce and am not able to pass the challenge. I have gone through it several times in case I missed something, but I'm sure I did everything correctly.
This is the error I am getting:
Dataset doesn't include 'Country,Flag_img_url and Sum of Value'. Please check the instructions.
I have made sure the dataset is named worldwide_sales_with_flags, saved in My Private App, and includes Country, flag_img_url, and Sum of Value. My charts also look identical to the screenshots provided in the instructions.
I am providing screenshots of my work and the error message below for clarity.
