I need to either resize my animation, or the stage.

I've nearly finished an animation. All clean. Save for it being just a tad too big for the stage, as part of it laps outside the stage sides. I've tried moving it by selecting all the frames, and moving them, but that only ever moves the last frame for some reason. I've tried using edit "multiple frames," and then ctrl+a, and resizing with transform, but nothing. Nothing works. I am raging because the support thus for has been pretty much an F-grade, and it's something that legitimately seems so simple. I've resized the stage, but all that ever does is make it bigger, and moves my animation off center, where (as previously stated), I cannot move the entire selection of frames, so the issue of it being out of stage is still very present. I am at my wit's end, someone please save me from this hellish, non-user-friendly program, and help me just get it sized right in the middle so I can finally publish this. Thank you in advance.
