What's the best way to remove letters and special characters from a string?

Thank you for your response! :slight_smile:

I’m not sure I understand you right, this is what I tried to do:

On my ‘Value 1’ I have the string ‘123M€’
On my ‘Characters to remove’ I have the string ‘abcdefghijklmnopqrstuvwxyz€$%’

I’m sure I’m doing it wrong cause it’s not working…
