Open frontPanel of SubVi displaying its current state

[H P]

Hello,

I have a SubVi within my MainVi which continuously calculates and displays stuff. In the MainVi I have a button, which when pushed should open the front panel of the subvi and display what ever it is doing at that point of time. 

I am able to just display its front panel but not able to display the calculations it is doing.

Thanks.

That's because your subVI is reentrant and you are opening a clone.

How can I solve my issue?

If I do not make the SubVi reeterant I get the follwing error:

LabVIEW:  (Hex 0x448) The Open VI Reference function cannot prepare a non-reentrant VI for reentrant run.

If you make your VI non-reentrant, then you have to change the options input of Open VI Reference to match. You have specified '8' and as the help explains, this will generate that error if the subVI is not reentrant.

Thank you.

I changed the 'option'  in Open Vi Reference to default.
