Just to illustrate what I said (note if you intend to modify the select pop-up, you will have to modify some counters in the inputLabel#_update js code accordingly),
<html>
<head>
<script>
function execReport(objid, param1, param2, param3, param4, param5)
{
if ('undefined' != typeof objid && null != objid)
{
var sURL = '?func=ll';
sURL = sURL + '&objId=' + objid;
sURL = sURL + '&objAction=runReport';
if ('undefined' != typeof param1 && null != param1) {sURL = sURL + '&inputLabel1=' + param1;}
if ('undefined' != typeof param2 && null != param2) {sURL = sURL + '&inputLabel2=' + param2;}
if ('undefined' != typeof param3 && null != param3) {sURL = sURL + '&inputLabel3=' + param3;}
if ('undefined' != typeof param5 && null != param5) {sURL = sURL + '&inputLabel4=' + param5;}
if ('undefined' != typeof param5 && null != param5) {sURL = sURL + '&inputLabel5=' + param5;}
sURL = sURL + '&nexturl=' + escape(window.location.href);
window.location.href = sURL;
}
}
// Other js code picked up from
function inputLabel1_update( changedField, form, newDate )
{
// ...
}
</script>
</head>
<body>
<form name="yourformname">
<SELECT class="searchBut" ID="inputLabel1_day" NAME="inputLabel1_day" onChange="inputLabel1_update(this, this.form, null)">
<!-- the rest of the select and option fields you have copied from the input page of your LiveReport -->
<!-- finally, a link or a button -->
<a href="javascript:execReport('123456', document.forms.yourformname.parameter1.value, document.forms.yourformname.parameter2.value)">Click here</a>
</form>
</body>
</html>
