Question

I have the following function that is suppose to take a value from a field in a form and assign it to a hidden field when its called. for some reason its not working and I cant give you more details on why its not working simply because javascript doesnt really tell you much about whats wrong.

function clickChange(stype){

    if(stype == '1'){
        var fValue = document.getElementById('checkB1').value;
        if(fCatValue == 0){
            fCatValue = fValue;
        }else{
            fCatValue = 0;
        }
        document.getElementById('cat_1').value = fCatValue;
    }elseif(stype == '2'){
        var sValue = document.getElementById('checkB2').value;
        if(sCatValue == 0){
            sCatValue = sValue;
        }else{
            sCatValue = 0;
        }
        document.getElementById('cat_2').value = sCatValue;
    }
}

You need to convert the values to integer, or treat them as a string:

either:

var fValue = parseInt(document.getElementById('checkB1').value)
        if(fCatValue == 0){....

or

var fValue = document.getElementById('checkB1').value;
        if(fCatValue =='0'){...
