Challenge - GOT Snapchat Filter?

#1

I am not able to upload rgb.csv file on the site.
Error shown while uploading is “Can’t upload file”

there is another doubt regarding the format of upload. The formatting of .csv file in sample.csv is 0,0 so do we only require %1.1f or more decimal places can be included like %1.2f or %1.3f

#2

There is a back-end issue it will get resolved by tomorrow. There is no need to include decimal places.
