Count unique numbers in a list of number

Hello! I have a column of house numbers and I want to count how many physical numbers I need from 0 to 9. Do you know that I can do that? I don’t know how to get it.

Hi @Jorge_Pineda_Minguet

Im not sure to see the relation between the title of your post and the content :wink:

Could you please give an effective example and simulate the result you want ?
