Hi Sai,

There is a validation rule on account causing the problem..make sure the account number has only numeric value.

In order to check this challenge you need to remove the validation rule of account that you might have created for other challenges.If this does not work, I would suggest you create new trailhead playground and work for challenge.

Please mark it as solved if my reply was helpful, it will make it available
for others as a proper solution.

Best Regards,
