Because you have a typo in your code, probably from copying and pasting existing code. You have:

Global bat2.bat=New bat
bat2\frame=0
bat2\x=40
bat2\y=60
bat2\gfx=gfx_bat
bat2\lft =0
bat2\up =0
bat2\alive=1
bat1\id =2
bat1\xmax =40
bat1\ymax =220
bat1\xmin =40
bat1\ymin=60

when it should be:

Global bat2.bat=New bat
bat2\frame=0
bat2\x=40
bat2\y=60
bat2\gfx=gfx_bat
bat2\lft =0
bat2\up =0
bat2\alive=1
bat2\id =2
bat2\xmax =40
bat2\ymax =220
bat2\xmin =40
bat2\ymin=60

It's a common mistake. :)
