Hi,
I have been searching for related topics and tried to mimic what other config the list box and action tool, but my workflow still doesn't work. I hope someone could help me figure out what is wrong.
So basically I want to have the option to choose multiple items from the list box and use them to filter to get the results associated with those chose values. The workflow is attached and the screen shot is here:

It would be really appreciated if someone could help out on this.
Thank you,
Blake
