So.. you want to zoom in ALT mode?
That wont work anyway.
You do the override settings, script loading, bracketing settings - whatsoever related to settings - in the ALT menu. To continue normal shooting (zooming, focusing, actually taking an image) you need to leave the alt mode again.
Besides from that, your lens had an error.. it was stuck at some point. The date on which the error occur is usually written in a third line, means below the "ZoomLensError" string..
