IEFormElementSetValue error when used multiple times

[marsol]

I'm receiving this error when I use the _IEFormElementSetValue more than once for the same field.

"IE.au3 Error from function _IEFormElementSetValue, $_IEStatus_InvalidObjectType"

The bulk of the original script was kindly provided by SandyD in this post http://www.autoitscript.com/forum/index.php?showtopic=38605

My problem arises when I run a loop trying multiple cabin numbers. Here's a somewhat simplified version of the script that demonstrates the same problem.

CODE

#include <IE.au3>

HotKeySet("^!x", "MyExit")

$oIE = _IECreate ("http://www.carnival.com/BonVoyage/AddToCart.aspx?pid=745")

_IELoadWait ($oIE)

; Create a variable to store the form

$oForm = _IEFormGetObjByName ($oIE, "addToCartSearchResults")

$BookNumField = _IEFormElementGetObjByName ($oForm, "AddToCart1:bookingNumber")

_IEFormElementSetValue ($BookNumField, "6x14v1")

$CabNumField= _IEFormElementGetObjByName ($oForm, "AddToCart1:cabinNumber")

$cabnum=1000

While 1

_IEFormElementSetValue ($CabNumField, $cabnum)

; Submit the form

_IEFormImageClick ($oIE, "AddToCart1:btnSubmit", "name")

; wait until webpage has loaded

_IELoadWait ($oIE)

; get html from page and check if 'Invalid Booking and/or Cabin Number' text is found

$sHTML = _IEDocReadHTML ($oIE)

If StringInStr($sHTML,"Specify Delivery") Then

MsgBox(0,'','Found')

Else

MsgBox(0,'','NOT Found')

EndIf

$cabnum=$cabnum+1

Wend

FileClose($file)

Func MyExit()

msgbox(1,"lll","exiting")

Exit

EndFunc

; Finished!

I've tried explicitly declaring the variables but that didn't seem to help. What am I doing wrong?

Thanks,

Okay, so I guess this is what I wasn't doing right. I need to have these two statements within the loop for it to work.

$oForm = _IEFormGetObjByName ($oIE, "addToCartSearchResults")

$CabNumField= _IEFormElementGetObjByName ($oForm, "AddToCart1:cabinNumber")

With my admittedly limited understanding I thought $oForm and $CabNumField were object variables and that these were persistent. Obviously some part of my understanding is wrong.

put "" around the 1000 for $cabnum

Correct. When the page reloads the previous document is destroyed and a new one created. Thus the object references to the elements on the page need to be re-established because the previous objects are no longer valid.

Thanks Dale,

That makes sense, of course. I'm amazed at the power of autoitscript and it's extensions.
