[Update form input field]

Worked like a dream

[Update form input field]

I have a form that updates a total based on the fields values entered on a form when the user leaves each field.

This works fine but I also want to update one of the entry fields which is a percentage of another.

 

I have in my js

 

   var theForm = document.forms[frm];

   var eTotal = theForm.elements["Total"];

    var ePremium = theForm.elements["Premium"];

    if (eTotal.value > 0) {

        var PremAmount = parseFloat(eTotal.value * ePremium.value / 100);

    }

 

    var divobj = document.getElementById('PremAmount');

    divobj.innerHTML = PremAmount.toFixed(2);

 

 

Which is called with

onblur="addPrem('totals')"

 

The original value in the totals field from the MySQL table is 770.00

This produces the following html page

<input name="PremAmount" tabindex="1" class="ent" id="PremAmount" size="2" value="77.00">

 

When I change the total to 888.00 I get the following 

 

<input name="PremAmount" tabindex="1" class="ent" id="PremAmount" size="2" value="77.00">88.80</input>

 

So it looks like it's working but writing a div rather than into the field itself

 

Can anyone help me with this please
