saving data in Master Slave Structure

[becidea]

Dear All,

I have a Master Slave Structure. I am going to save my data to file, and I am using sub.vi to calculate data. But here I couldn't insert this sub.vi's fila save option. I attached the Slave structure of vi and Sub vi which is in Slave Struture. Please advice me to solve this problem.

Best.

Can you save the vi's instead of pictures.

I have an idea why it does not work as you expect.
