Hi all.

 

I've got a weird little javascript issue here that's confusing the hell out of me. My maths can't be so bad that I can't work out a simple percentage! Box 1 is calls offered, box 2 is calls answered. All I want box 3 to do is show the call answer rate, so (box 1 / box 2) * 100 = box 3.

I put 100 in the first box, 95 in the second, which should mean the last box outputs 95%. BUT... I get "105.26315789473683"

Here's the .js file running the script:

 

function startCalc(){
 interval = setInterval("perc()",1);
}

function perc() {
a = document.evening_summary_form.existing_offered.value;
b = document.evening_summary_form.existing_answered.value;
c = a/b;
d = c*100;
document.evening_summary_form.existing_answer_rate.value = d
}

function stopCalc(){
 clearInterval(interval);
}

 

And here's the section of the form it relates to:

 

<td align="center" class="">
             <label>
               <input name="existing_offered" type="text" id="existing_offered" size="4" onFocus="startCalc();" onBlur="stopCalc();"/>
             </label></td>
             <td align="center">
             <label>
               <input name="existing_answered" type="text" id="existing_answered" size="4" onFocus="startCalc();" onBlur="stopCalc();"/>
             </label></td>
             <td align="center">
               <label>
                 <input name="existing_answer_rate" type="text" id="existing_answer_rate" size="3" readonly="readonly" />%
               </label></td>

Try this instead

 

(box 2 / box 1) * 100 = box 3.

 

At present it is 100 divided by 95, times 100 = 1.052631578947368

 

You need 95 divided by 100, times 100 = 95

Yeah I'm a dumbass!! I tried that twice but wasnt checking the file back in. It's working now... I knew I couldn't be that stupid, but clearly I am haha

It's easy enough to do. Sometimes we get caught up in the minutiae and miss the obvious.
