Strange Javascript Error in IE

[Jenosavel]

I'm getting an Expected Identifier error in IE. Usually this is a relatively simple thing to fix, caused by an extra comma or accidentally using a keyword for a variable name. However, this time I'm really quite stumped as to what's causing it. It's coming up from the second line in the following code:

for (i=0;i<allinputs.length;i++) {
     newgriff = document.createElement("input");
     newgriff.type="hidden";
     newgriff.class="ordgriff";
     newgriff.name="g"+i;
     newgriff.value=allinputs[i].id.substring(3);
     p.appendChild(newgriff);
}

i, p, allinputs, and newgriff are previously defined variables.

Anyone know what's causing the error?
