frist try to change the numbers you grab from thext fields with parseInt() function

element.innerText will give you the output in string format. You have to first convert that value to integer using parseInt. Then only you can operate arithmetic operators on them.

 var LANUser = document.getElementById('ContentPlaceHolder1_MainContent_grdAddonModules_txtAdditionalLANUser_' + j).value;
             var MinLANUser = gdv.rows(i).cells(2).innerText;

convert these to integer type.

     var LANUser = parseInt(document.getElementById('ContentPlaceHolder1_MainContent_grdAddonModules_txtAdditionalLANUser_' + j).value);

var MinLANUser = parseInt(gdv.rows(i).cells(2).innerText);
