HSDIO initializing acquisition and generation tasks in parallel while loops

Hi NI Community,

I'm using the example “Dynamic Generation and Acquisition Demo.vi” to write this program.

I'm trying to set 2 while loops. One for acquiring data and one for generating high/low logic. 

However, I'm having issue with the generation loop. Please see attached for my program.

Here is the example VI I'm talking about

Thank you!
