If..else condition error

I am trying to figure out what is wrong with this following code. The code searches for value in a table and assigns mxCost. The IF..ELSE condition works for all values except 1 and is also reading the table. The IF condition makes the page crash and i am not able to figure out why? Can someone please help me figure out what i am doing wrong here. Any help will be appreciated. Thank you.

What I have tried:

$jq("#airTableValues tbody tr").each(function() {
         var monthName  = months[parseInt(dateSplit[1])-1]+" "+dateSplit[0];
         if(monthName==$jq(this).find("td:eq(0)").text().trim())
          {
              mxCost = $jq(this).find("td:eq(6)").text().trim();
          }
      });
 
    if (mxCost)
      mxCost = (mxCost.substring(1, mxCost.length));
    else {
      mxCost = 0;
    }


  
    var MxStat = document.getElementById("MxStat").value;
    MxStat = MxStat/100;
    var InflationRate1 = document.getElementById("InflationRate1").value;
    InflationRate1 = InflationRate1/100;

    var rate3 = document.getElementById("rate3").value;
    rate3 =   Math.pow(1+rate3/100,1/365)-1;
    var mxAdj;
    if (MxStat == 1){
       mxAdj = mxCost;
    } //NOT WORKING!
    else (MxStat != 1) {
      var TotalCost = mxCost * 2; 
       mxAdj = (TotalCost * MxStat) - mxCost; 
    }


    var ReturnVal = (mxAdj * InflationRate1) + mxAdj;
    var ReturnCalc = ReturnVal * 1000000;
    var ReturnPV = Math.floor(ReturnCalc/Math.pow(1+rate3,periods));
    document.getElementById("ReturnCondition").value = 
    (ReturnPV/1000000).toFixed(2);
    ReturnCondition = ReturnVal.toFixed(2);
