Transfer random listbox items to new listbox and then loop through selected items

I'm trying to run a loop against items that were selected in one listbox (lboMonthList) and transferred to a new listbox (lboMonth). Right now, the code is just running the loop on the single item highlighted in the lboMonthList listbox. I don't know how to change my code to get it to run against the lboMonth items instead. File attached.

End result, if Oct - Dec are transferred to the new list box, I want my code to run Steps 3-5 against Oct-Dec. I don't want it to loop against the original listbox (lboMonthList).
