1) If you are wanting to join the arrowhead end of a rate (that drops into a cloud), using the Hand tool, drag the arrowhead of the rate onto your box variable, or
2) If you don’t have an arrowhead (pipe comes out of a cloud), or even if you do have an arrowhead, using the Merge tool, drag and drop the box variable onto the arrowhead or cloud.
3) PLE and PLE Plus do not have a Merge tool. To connect a box variable to the cloud of a previously inserted rate, select the Rate tool, click on the box variable and then click on the valve of the rate (not on the cloud). Then use the Delete tool to delete the cloud.
