Variable is losing value after second loop iteration.

[Vanecelli]

The below code is calling a function that populates a certain number of listbox es with options. IT loops as it should if there are only 2 instances of k, but anything greater and the second variable being passed, document.getElementById(), loses value, so the populateList function cannot find ANY of the elements.

 if (tip>1){
 document.getElementById("grpbook").style.visibility="visible";
 document.form1.unit.style.visibility="visible";
 removeChildren(trow);
 removeChildren(grow);
 addcolumn('indguest', gtg, 'glft', 2, 'glft');
 addcolumn('indguest', gt3, 'l', 3, 'gname');
 addcolumn('glist', '<strong>Guest List:</strong>', 'gllft', 1, 'grplist');
 addcolumn('glist', tmp, 'l', 4, 'gnlist');
     if (document.getElementById("air").checked){
    populateList("airforce", document.form1.Rank2);
        for (var k=0;k<tip;k++) {
        var gr="gRank"+k
            populateList("airforce", document.getElementById(gr));
        }
    }
    else{
    populateList("navy", document.form1.Rank2);
        for (var k=0;k<tip;k++) {
        var gr="gRank"+k
            populateList("airforce", document.getElementById(gr));
        }
    }
 
 }

Actually, I figured it out, albeit way late last night. :)
I was missing one lousy character in the elements name. Figures, looking for a big problem, and it's really simple. Thanks for the look anyway.
