Javascript checkbox problem

I have the following javascript to make checkboxes act like radio boxes (allow only 1 to be checked) which doesn't work. The condvals array contains the variable names:

function checkBoxValidate(cb) {
      var condvals=new Array("document.form1.conditioncancerBladder","document.form1.conditioncancerBrain","document.form1.conditioncancerBreast","document.form1.conditioncancerColorectal","document.form1.conditioncancerEndometrial","document.form1.conditioncancerEsophageal","document.form1.conditioncancerKidney","document.form1.conditioncancerLeukemia","document.form1.conditioncancerLung","document.form1.conditioncancerMelanoma","document.form1.conditioncancerNonhodgkinsLymphoma","document.form1.conditioncancerPancreatic","document.form1.conditioncancerProstate","document.form1.conditioncancerStomach","document.form1.conditioncancerThyroid","document.form1.conditioncancerOther");
      for (j = 0; j < 16; j++) {
            if (eval(condvals[j] +".checked") == true) {
                  condvals[j].checked = false;
                  if (j == cb) {
                        condvals[j].checked = true;
                  }
            }
       }
}

The input tags have
onClick="javascript:checkBoxValidate(0)"
onClick="javascript:checkBoxValidate(1)"
etc.

It produces no errors but doesn't work.
Thanks

It's a little cryptic-looking, but how about something like:

function checkBoxValidate(cb) {
var condvals=new Array("document.form1.conditioncancerBladder","document.form1.conditioncancerBrain","document.form1.conditioncancerBreast","document.form1.conditioncancerColorectal","document.form1.conditioncancerEndometrial","document.form1.conditioncancerEsophageal","document.form1.conditioncancerKidney","document.form1.conditioncancerLeukemia","document.form1.conditioncancerLung","document.form1.conditioncancerMelanoma","document.form1.conditioncancerNonhodgkinsLymphoma","document.form1.conditioncancerPancreatic","document.form1.conditioncancerProstate","document.form1.conditioncancerStomach","document.form1.conditioncancerThyroid","document.form1.conditioncancerOther");

oClicked = eval(condvals[cb])
for (j = 0; j < 16; j++) {
oJ = eval(condvals[j]);
oJ.checked = ( (j == cb) && oClicked.checked );
}
}
