I am adding labour charge to total paid amount using :
#include <IE.au3>
#include <Array.au3>
$oIE = _IEAttach ("Shop")
$oTable = _IETableGetCollection ($oIE, 1)
$aTableData3 = _IETableWriteToArray ($oTable)
Local $sitem1 = $aTableData3[5][1]
Local $sitem2 = $aTableData3[5][2]
Local $lcharge = "10" ;add manualy using inputbox, becuase not generating online
Local $atotPric = "Payable Total Price "
Local $oTds = _IETagNameGetCollection($oIE, "td")
For $oTd In $oTds
If $oTd.Innertext = $atotPric Then
$iatotPric = $oTd.NextElementSibling.innertext
MsgBox (0, "2", $iatotPric)
EndIf
Next
$irCtotal = StringFormat("%.2f", $sitem1 + $sitem2 + $lcharge)
$crTotp = StringReplace(_IEBodyReadHTML($oIE), $iatotPric, $irCtotal)
_IEBodyWriteHTML ($oIE, $crTotp)
But, It was also changing Total price, I want to change only Payable Total Price.
