sqlmap won’t give me results i’m looking for

I am trying to use sqlmap. Altho every times I use it, I just get a response of:

[13:39:11] [CRITICAL] previous heuristics detected that the target is protected by some kind of WAF/IPS   [13:39:11] [INFO] testing if the target URL content is stable  [13:39:12] [INFO] target URL content is stable  [13:39:12] [CRITICAL] no parameter(s) found for testing in the provided data (e.g. GET parameter 'id' in 'www.site.com/index.php?id=1'). You are advised to rerun with '--forms --crawl=2'  [*] ending @ 13:39:12 /2020-07-29/ 

I’m using the websites I find in the tutorials. But I always get this message. If not, it keeps asking me for stuff and then doesn’t work. Please help me. Heres the command I use: ‘python sqlmap.py -u "Enter-website-here"’. Heres the tutorial I’m using: https://www.binarytides.com/sqlmap-hacking-tutorial/
