HELP

I'm getting this error message when trying to schedule a meeting.  I followed the prompts to update the time zone but when I go to time zone it's correct.  Here is the error message:

User: arn:aws:iam::787345941828:user/web_user is not authorized to perform: dynamodb:Query on resource: arn:aws:dynamodb:us-east-1:787345941828:table/us05_ZMWEB_MTG_TEMPLATE with an explicit deny in a service control policy (Service: AmazonDynamoDBv2; Status Code: 400; Error Code: AccessDeniedException; Request ID: 2BDP70MJ0D4DAIM3QVM2UIGMDJVV4KQNSO5AEMVJF66Q9ASUAAJG; Proxy: null)

Please advise
