Using UserForm to set PageSetup properties

I have updated the worksheet for page orientation and print grid line. I took a swing at the dates issue, but I don't think I have it quite right. I'm not very good at the user validation part. Is there a reference guide on that for common validation coding?

I went ahead and attempted to place the form into a Tab in Excel after figuring out how to "Save" data to a worksheet using ControlSource. The issue I came across is that the worksheet doesn't seem to appear when in XLAM form. Is there a better way? It works perfectly in a normal worksheet, but the end goal is to place several macros into a tab for multiple people to use as shortcuts.
