Route items based on whether or not a label exists

Hello! I am hoping to route items using decision points based on whether or not a label exists. I have created this model as an example - my aim is to route the box objects to Queue1 if they have the label 'destination' and to Queue2 if this label does not exist on the object. Thank you in advance.

Thanks for your response, @Jörg Vogel! When I add this to my Send Item condition I receive the following error message:

Flexscript Error MODEL:/DP1>variables/localType/onContinue invalid character <â> ascii = -30

Flexscript Error MODEL:/DP1>variables/localType/onContinue invalid character <€> ascii = -128

Flexscript Error MODEL:/DP1>variables/localType/onContinue invalid character <œ> ascii = -100

Flexscript Error MODEL:/DP1>variables/localType/onContinue invalid character <â> ascii = -30

Flexscript Error MODEL:/DP1>variables/localType/onContinue invalid character <€> ascii = -128

Flexscript Error MODEL:/DP1>variables/localType/onContinue

Could not finish parsing because of previous errors.

Did you copy the source code from the internet page or did you write it yourself?

Yes, good point! After writing it myself I receive different errors:

Great question! This can be accomplished using the assert method on the item destination label in decision point DP1's On Arrival trigger. This will attempt to retrieve the label value if it exists, and if it does not, it will create the label and set its value. Please take a look at the attached model and see if it meets your needs.
