Why won't my button hide?

[eath]

I'm at a loss after trying to build this for several days. Experts, please point out my error?

Code: Select all

screen inv_grid:
    hbox:
        xalign .5 # center generally
        # tried grid and vpgrid
        # vpgrid:
        #    cols num_columns
        for i in range(4): # or whatever
            hbox:
                python:
                    tag = "slot_{}".format(i)
                    if not renpy.get_screen(tag): # I think this means if it can't find this screen, then:
                        renpy.use_screen("inv_slot", tag=tag) # make new screen. can't use show_screen, shows nothing

screen inv_slot(tag):
    tag tag # getting desperate
    hbox:
        xalign .5
        # at inv_animation
        imagebutton:
            focus_mask True
            idle "item.png"
            action [Hide("tag"), Play("sound","click.wav")] # click plays sound, does not hide

label start:
    scene bg uni
    show screen inv_grid

    pause

    "You've created a new Ren'Py game."

Tags are still a mystery to me, their documentation is sparse AFAICT. And I can't Google the forum for threads on it because every single indexed page contains the phrase "Use the code tag to format scripts." I can't disallow that search phrase because again, every single page...

My thanks to the people on this board who have patiently helped a noob get this far.
