Dunno if you’ve seen this answer or not; I don’t see it in the thread; the 1 stitch you seem to be missing is one I also missed at first:

In the CROP tool, the only time you see the option to CLEAR either “width” or “height” is when you first open the tool. Once you start dragging a marquis to set those params visually, that option goes away.

One more thing you may or may not already know; you can make those tool options (and all the pallets) appear and disappear by toggling the TAB key …unless of course you happen to be in the type tool … oooops… If you accidentally or otherwise made the tool options disappear, you can toggle them back again.

Just 1 more thought: there are no stupid questions.
