Relational expression about the state of the crane

Hicollision.fsm

I get the current state of the crane in the model.

Then I want to add a label to the crane according to the current state of the crane

But it shows an error, how should this expression be written?

Software Version:

FlexSim 23.1.2

The state string value "offset travel empty" or any string has to be in double quotes.

if(Model.find("Crane3").as(Object).stats.state().valueString=="offset travel empty")

To add to this:

A slightly cleaner approach might be to use the numerical state value and compare it to the respective define. This might prevent typos and probably runs slightly faster.

if(Model.find("Crane3").as(Object).stats.state().value == STATE_OFFSET_TRAVEL_EMPTY)

Thank you very much for your guidance, but the label on the crane still does not change, what is the reason?

Use ".value" when comparing to the state number, not ".valueString".
