Hi everyone, I keep receiving the same error message when I go to verify the Distribute the flow with a custom button unit in the Build a discount calculator module. The error message is as follows: There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Account number must be 8 characters long: []

Can anyone please shed some light as to why this is?

Thank you!

I am getting the error: Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Discount_Percent__c]: [Discount_Percent__c]

Throughout this module I've been using Discount Percentage, not Discount Percent, but when I made an opportunity for Edge Communications - 1 year contract it required me to add a discount percent manually. I'm not sure what is wrong or what to do. Please help!
