Hi..

I have this function:

Code:
function doz(oText){
    var P27_max = document.getElementById("P27_max").value;
    //var P27_max_convert = parseFloat(P27_max) + parseFloat(1); 
    var P27_max_convert = ((parseFloat(P27_max) * parseFloat(1000)) / parseFloat(0.00) / parseFloat(12));  
    if( !isNaN(P27_max_convert) ){
    var P27_maxdoz = document.getElementById("P27_maxdoz").value = P27_max_convert.toFixed(2);
    }

    var P28_max = document.getElementById("P28_max").value;
   // var P28_max_convert = parseFloat(P28_max) + parseFloat(2);
    var P28_max_convert = ((parseFloat(P28_max) * parseFloat(1000)) / parseFloat(22.00) / parseFloat(12));    
    if( !isNaN(P28_max_convert) ){   
    var P28_maxdoz = document.getElementById("P28_maxdoz").value = P28_max_convert.toFixed(2);
    }
}
my output is Infinity..

what's wrong in my computation :

var P28_max_convert = ((parseFloat(P28_max) * parseFloat(1000)) / parseFloat(22.00) / parseFloat(12));

Thank you
