I cannot wire a boolean output to a terminal of a sub vi

[lv_datataker]

I have a sub vi, which I would like to use to remember the previous boolean state, and indicate if it has changed from the previous value.

For some reason, I cannot wire the output value, to a terminal of the Sub VI. The boolean value is an output from a shift register, from a while loop.

I have included my sub vi, and it was created in LabVIEW 6.0.2.

Could someone be able to give me a tip whats going on?

Thanks,

Anthony

I can wire the output "new value" to an indicator with no problem. However, you don't have the control "Boolean Value" wired to anything on the subVI connector pane and the convention for outputs is on the right side of the connector pane and you have it on the left side. I suspect you intended to wire "Boolean Value" where you have "new value" wired and meant to wire "new value" to the empty position on the connector pane. Fix those and you should be OK.

Thanks,

It makes me realise, often you miss the simplest thinks.

I'll make sure I examine my sub vi's more closely.
