For those that want to know how to cycle through a selection

I have some code that selects sheets by sheet name. But I
also want to select some other sheets if they are not
blank. The user will click on a button to do this and then
I want to print all those sheets selected. I can do all
of this apart from selecting the sheets that are not blank
