Trouble create a battle.net account

I’ve been trying to make an account for my friend because he struggled for about an hour. I tried to help him by making one for him but every time I finish the humanity test it keeps showing “Value is invalid”.
Any suggestions on what to do?

I am also having the same issue today. 5/2/2024

Same problem and no one on blizzard seems to care to help. My best friend has not been able to make an account no matter what we do. value is invalid is what is said each time we do that stupid human verification. I’m going to be requesting a full refund if this is not fixed by this weekend.
