FlexScript exception: Label property ItemsType retrieved on /Combiner2/Product.

Hello,

I encounter a problem while running the attached model. The process is running correctly, but I get an error message:

"FlexScript exception: Label property ItemsType retrieved on /Combiner2/Product. Label does not exist. at MODEL:/Tools/ProcessFlow/ProcessFlow/Assign Labels>labels/1/2". (ERROR)

ItemsType is a label on CUtote (FIG). I really don't know why I get this error!

Please help me to understand the problem.

Regards.

You are getting this error because the token in Process Flow is being created everytime an item enters Combiner 2. The boxes do not have the "ItemsType" label, so that is why the error is coming up. To fix this you can set a requirement to only create that token when it comes from the first input port.

You should post this as a new question - not an answer to an old question.

There's an option for this in the processor properties cycletime options:
