Adding two fields together on the add page

Hi,
use custom JavaScript code for this purpose.

Here is a sample:

<script language=javascript>

You can add JavaScript code at the end of the page on theVisual Editor tab in HTML mode.

See Below.

For some reason, it doesn't actually do any math. When I type in a value in the first field, like 32, then 32 in the next, the result is 3232. All it is doing is placing the numbers right next to each other.

It's easier just to do the math in the SQL query. I would still like to see if the Javascript would work though.

Hi,
try to use toFixed() function:

x.onchange=x.onkeyup=y.onchange=y.onkeyup=function()

More info here:

It's easier just to do the math in the SQL query. I would still like to see if the Javascript would work though.

here's some calcs I used in 3.2 jsfunctions.js
function UpdateLabourTotal()

{

var lt;

var lt1;

var lt2;

lt1 = document.editform.Rate.value document.editform.Hours.value;

lt2 = document.editform.SetRate.value document.editform.SetHours.value;

lt = parseFloat(lt1) + parseFloat(lt2);

return lt;

}
function UpdatePartsTotal()

{

var pt;

var pt1;

pt1 = document.editform.PartPrice.value document.editform.Quantity.value;

pt = parseFloat(pt1) + parseFloat(document.editform.Price.value);

return pt;

}
function UpdateGSTTotals()

{

var gstt;

var gst1;

var gst2;

var gst3;

gst2 = UpdateLabourTotal();

gst3 = UpdatePartsTotal();

gst1 = parseFloat(gst2) + parseFloat(gst3);

gstt = gst1 document.editform.GST.value;

return gstt;

}
function UpdatePSTTotals()

{

var pstt;

var pst1;

var pst2;

var pst3;

pst2 = UpdateLabourTotal();

pst3 = UpdatePartsTotal();

pst1 = parseFloat(pst2) + parseFloat(pst3);

pstt = pst1 * document.editform.PST.value;

return pstt;

}
function getLabourPartsTotal()

{

document.editform.LabourTotal.value = UpdateLabourTotal();

document.editform.PartsTotal.value = UpdatePartsTotal();

document.editform.GSTTotal.value = UpdateGSTTotals();

document.editform.PSTTotal.value = UpdatePSTTotals();

var var1;

var var2;

var var3;

var var4;

var1 = UpdateLabourTotal();

var2 = UpdatePartsTotal();

var3 = UpdateGSTTotals();

var4 = UpdatePSTTotals();

document.editform.Total.value = parseFloat(var1) + parseFloat(var2) + parseFloat(var3) + parseFloat(var4);

}

I struggled with this as well and performed the following modification that seemed to correct the problem.

Modify code as follows:
<script language=javascript>

var x = document.forms.editform.value_FieldName1;

var y = document.forms.editform.value_FieldName2;

x.onchange=x.onkeyup=y.onchange=y.onkeyup=function()

{

document.forms.editform.value_FieldName3.value = document.forms.editform.value_FieldName1.value1+document.forms.editform.value_Fie

ldName2.value1;

}

</script>
