Insert blank column and copy/paste values

If anybody would be willing to help, again, what I'd like to have done is to have a blank column inserted between columns W and X(these values change so the VBA statement should reference the end of the columns) and the values that are now in column Y(April 17th values) pasted as values into the now empty column X. I would like to do this for tabs Ann-Sheet 2. I'm having a bit of trouble with setting up the loop that would go through the desired sheets.
