Beste allen,
Ergens gaat het niet goed.....
Ik heb een script van https://inorganik.github.io/countUp.js/
maar ik kan dit totaal niet verwerken in een blanco webpage......
Wat heb ik?
HTML
En dan de javascript:
Maar ik krijg niet de teller met de gegeven dingen. Whats wrong with me????
Ik hoor graag van mijn redder
Groet,
