New Post: Error when task name is a number

I'm running into an issue when the task name is a number only. When passing this through as taskservice.rootfolder.tasks("TaskName") I get an error that "Value does not fall within the expected range." as it is seeing the name as a number instead of a string. I am passing it as a string so I'm not sure if anyone else has seen this issue.

Any help would be appreciated.

Thanks,
