Try Catch with Nested ForEach

Hi ,I have the following code which checks for scheduled tasks on a list of computers and returns those which were not created by Microsoft and run as administrator. 

I'm trying to write any errors to $ErrorLog. It works if the server is not contactable or if access is denied as it writes the error to $ErrorLog and carries on with the next computer.

I have some machines that are returning an error (nError:ERROR: The task XML contains a value which is incorrectly formatted or out of range) on one of these machines (at least) there are scheduled tasks which are in a valid format but these then end up printed to the screen rather than the task details being output to a file. I tried moving the 'Try/catch' to inside the 'foreach ($task in $tasks)' but the first error caused the script to end completely.

Any help greatly appreciated as this is causing just a little frustration! please do the 'idiot' guide approach if replying as I'm new to this.

Thanks.

Pete.
