Help with a part of code - working with strings - JavaScript and CSS

Hi all,

I trying to get the following code working... no success yet, so I suspect a formal error in the code somewhere.

<html> 


<head> 

<script> 

var czUspresence as int 

var czUscontrol as int 

var czUssrpresence as int 

var czUssrcontrol as int 


function euGetstatus(){ 

   var czUs = document.getElementById("cze_us").value; 

   var czUssr = document.getElementById("cze_ussr").value; 

   var sumCz = parseInt(czUs,10) - parseInt(czUssr,10) 

    

   if (sumCz < -2) 

   {czUssrcontrol = 1 ; 

   czUscontrol = 0; 

   czUssrpresence = 1; 

      if (czUs > 0) 

      {czUspresence = 1; 

      } 

   } 

   else if (sumCz > 2) 

   {czUscontrol = 1; 

   czUssrcontrol = 0; 

   czUspresence = 1; 

      if (czUssr > 0) 

      {czUssrpresence = 1; 

      } 

   } 

   else if (sumCz <> 0) 

      {if (czUs>czUssr) 

      {czUspresence = 1; 

      } 

      else 

      czUssrpresence = 1; 

      } 

   } 

    

   document.getElementById("euUsregular").value = sumUspresence; 

   document.getElementById("euUsbattleground").value = czUscontrol; 

   document.getElementById("euUssrregular").value = czUssrpresence; 

   document.getElementById("euUssrbattleground").value = czUssrcontrol; 

} 


</script> 

</head> 


<body> 


<select style="position:absolute; left:919px; top:286px; background-color: blue; color: white;" id="cze_us" class="us" onchange="euGetstatus();"> 

<option selected>0 <option>1 <option>2 <option>3 <option>4 <option>5 <option>6 <option>7 <option>8 <option>9 <option>10 <option>11 

</select> 


<select style="position:absolute; left:956px; top:286px; background-color: red; color: white;" id="cze_ussr" class="ussr" onchange="euGetstatus();"> 

<option selected>0 <option>1 <option>2 <option>3 <option>4 <option>5 <option>6 <option>7 <option>8 <option>9 <option>10 <option>11 

</select> 


<input type="text" id="euUsregular" style="position:absolute; left:550px; top:150px;  background-color: cyan; color: black" readonly=true size="2" value="" align="center"/> 

<input type="text" id="euUsbattleground" style="position:absolute; left:550px; top:180px;  background-color: cyan; color: black" readonly=true size="2" value="" align="center"/> 

<input type="text" id="euUssrregular" style="position:absolute; left:600px; top:150px;  background-color: pink; color: black" readonly=true size="2" value="" align="center"/> 

<input type="text" id="euUssrbattleground" style="position:absolute; left:600px; top:180px;  background-color: pink; color: black" readonly=true size="2" value="" align="center"/> 


</body> 

</html>

Can someone help with finding the error and/or correcting any mistake in there?

What I am trying to do is to check the two values (cze_us and cze_ussr) to see, which one is bigger and also their difference. One of the breaking points is (-)3, where the respective country would get cz****control and also cz****presence equal to 1.

When the difference is less then 3 and a country has more than 0 (cze_us or cze_ussr), that country gets only cz****presence equal to 1.

If a country has its cze_us(sr) value equal to 0, it does not get any cz****presence or control.

Hope I am clear ;)

else if (sumCz <> 0) { if (czUs>czUssr) { czUspresence = 1; } else { czUssrpresence = 1; } }
