Question about Calculation

Hello all,

I would like to have a subtotal in each repeat line item the xhtml code as below:

<xforms:header>
<xforms:bind id="linetotal" nodeset="ChargeAmount" calculate="Quantity * Amount" />
</xforms:header>
:
:
<xforms:repeat model="model_Document" id="repeat_LineItem_model_Document" nodeset="/Document/Body/PurchaseOrder/LineItem">
:
<xforms:output ref="ChargeAmount" model="model_Document" xxforms:format="format-number(.,'####,####0.##')">
<xforms:label>Charge Amount</xforms:label>
</xforms:output>
:
</xform:repeat>
:
:

however, it cannot auto update the value of ChargeAmount when I change the value of Quantity or Amount. Please advise anything I have done wrong?

Thanks a lot!!

The bind looks incorrect:

<xforms:bind id="linetotal" nodeset="ChargeAmount" calculate="Quantity
* Amount" />

The expression in "calculate" evaluates relative to ChargeAmount, so
as it is right now it will look for child elements Quantity and
Amount. Maybe instead you want to have: ../Quantity * ../Amount.
