I assigned a number of operators based on man-hours needed for the process. In an assign box I have divided the total number of man hours by 12 and use "ceil" to round the number up. So the label "finishingOps" looks like
ceil(getlabel(token, "totalManHours") / 12)
The token then moves to a subflow where I want to get the quantity from the label "finishingOps". I know the value is placed on the label because the token reads finishingOps 13.0000 when I click on it. But the subflow stops once it reaches this step.
