Starting an array of DAQmx tasks throws error 50103 on start

Question

Hello,
I am creating and starting a number of tasks from an enum array which will be subsequently used to read data from devices.  The issue is that the second iteration of the starting loop throws error 50103 (specified resource reserved).
When I carried out some testing I discovered that the tasks are set up correctly and the error is thrown only on the start task.
I have attached the section of code for reference. 
Thanks
Dave

Answer 1

I have to call the start vi more than once as the tasks are contained within an array.  As I understand (but suspect I may be incorrect), that for each case corresponding to the input enum array, the task within that case is started (once) due to the auto indexing of the array.
This is a subVI which is only called once in the application.  The output from this should be a list of started tasks which I use in subsequent read operations until the program is complete, where the tasks are then cleared down.
Apologies if I have repeated myself, but I am trying to understand how this works, since what I am seeing does not seem to make any sense to me.
