Hi All, new to Salesforce Development

I'm trying to create an Apex Trigger in Task(Activity)/Event object.

1) Check a field in Account (Number Field A__c) if more than 100
2) Check a field in Account (Number Field B__c) if more than 50

Basically I have criteria above if not pass, prompt error message to users upon saving their Task/Event record.
