Hello;

I am a newbie in flexsim and following a youtube video tutorial with the title "Dev Talk: Kiva System Modeling" but I am getting error messages after setting alpha values at https://www.youtube.com/watch?v=3AQ-cjOS9tY&t=446s
Below are the error messages that I am receiving for all my carts. Could you please help me?

time: 0.000000 exception: FlexScript exception: label Item doesn't exist on token id: 1 at MODEL:/Tools/ProcessFlow/FloorStorage1 Process/Set Cart Color>variables/codeNode time: 0.000000 exception: FlexScript exception: label Item doesn't exist on token id: 1 at MODEL:/Tools/ProcessFlow/FloorStorage1 Process/Set Alpha>variables/codeNode

You create a cart and assign it to a label called Items but then try to access it using 'Item'
