html Bootstrap carousel (slide in bootstrap)

Please help with this code. I have three items and I want when I press next or previous it passes to an another item but it didn't work it stays fixed at the item 1. I already compared my code with many other codes and it seems to me right. It's a simple carousel with two buttons next and previous but nothing happened when I press them

I'm guessing you are using Bootstrap version 5?

If so, a few things to check:

• In the Bootstrap carousel example, the carousel uses data-bs-slide-to = "1" on the next button your one is data-slide-to="1", it's missing the 'bs' and that's the same with data-bs-ride and data-ride.
• Check you correctly included the necessary Bootstrap JS file
