I am getting an error ‘pic1 has no properties in this code’, which is supposed to float a gif file (alien.gif in this case) around the screen. The code works fine in IE, but in Netscape and Firefox I get the following error:
Error: pic1 has no properties
Line: 66
Which is this line:
pic1.moveTo((x+pageXOffset),(y+pageYOffset))
I thought pic1 was defined with this line in the header:
var pic1=eval('document.'+_all+'pic1'+_style);
(Scratching head)
I have pasted the code below. Any help anyone can lend would be greatly appreciated.
Thanks.

PS I did not write this code originally I'm just trying to get it to run.
