AGV not working properly in process flow

hi~I am currently working on a model that is using 2 AMR to send items from designated place to another designated place at a fixed time (I used a global table to do so). In my process flow, I used the split activity, the left side is for agv1 and the right side is for agv2.

After I run my model now, it will show this error message:

my amr2 can not move after loading item, but in the process flow I see the token is correctly labeled.

I have no idea about the error appearing now, hope to get some suggestions~ thanks!

this is my model: 1009_two_car.fsm

Software Version:

FlexSim 18.0.10

You should fix your exceptions before posting the model if you can. They may be telling you what the problem is:

time: 115.415509 exception: FlexScript exception: Retrieving from2 label property on node that does not exist at MODEL:/Tools/ProcessFlow/ProcessFlow/Load~2>variables/involved2
time: 115.415509 exception: FlexScript exception: Retrieving to2 label property on node that does not exist at MODEL:/Tools/ProcessFlow/ProcessFlow/Travel~4>variables/involved1

In this case you're trying to reference the first token's labels but you've deleted it with the left sink. Since you copied the labels why don't you just access them directly?

token.to2
token.from2
