AYAAKI

For some reason I am unable to select my viewport in my sheet layers. I can't select in order to annotate and crop or move the viewport around the sheet layer. I feel I've exhausted my resources as far as co workers and searching the forum so apologies if this question has been answered a million times and I missed it. Do I have some settings box checked off? I can't attach the file to a public forum just yet as this production is still upcoming. Please let me know, thanks!
