SlideImage Subobject

[MARILY ILLESCAS]

Hello! Hope you can help me.
I'm making a memory experiment, in the encoding phase are two images
that should be classified as same or different.  In the recognition
phase are two images, one must decide which image is old or if both
are new. The problem is that in the recognition phase I want the
program select randomly one of the two images presented in the
previous stage to be presented with a new image. Use a slide with
three objects, each corresponding to the three options (old image 1,
old image 2 and new image). I use this script to select randomly the
old image and the position (is only a part):


Set RImg1 =
CSlideImage(EstimulosR.States(EstimulosR.ActiveState).Objects("RIm1"))
Set RImg2 =
CSlideImage(EstimulosR.States(EstimulosR.ActiveState).Objects("RIm2"))
Set NImg =
CSlideImage(EstimulosR.States(EstimulosR.ActiveState).Objects("NIm"))

stims = c.GetAttrib("StimType") If stims = "1" Then
stim = 1
Else
stim = 2
End If

SelectPosition:
pos = PRNG.Random(1, 2)		'Select a position

SelectOld:
OldStim = PRNG.Random(1, 2)		'Select a old image

If pos = 1 And OldStim = 1 And stim = 1 Then
	pos1= pos1 + 1
	OldStim1 = OldStim1 + 1
	If pos1 > 10 Then
	GoTo SelectPosition
	If OldStim1 > 10 Then
	GoTo SelectOld
	Else
	'RImg1.Filename = c.GetAttrib("RImagen1")
	'RImg1.Draw
	RImg1.X = "441"
	RImg1.Y = "384"
	'NImg.Filename =c.GetAttrib("NImagen")
	'NImg.Draw
	NImg.X = "589"
	NImg.Y = "384"
	c.SetAttrib "Location", "1"
	c.SetAttrib "PosOld", "1"
	Debug.Print c.GetAttrib("PosOld")
    End If
	End If
End If


If pos = 2 And OldStim = 1 And stim = 1 Then
    pos2= pos2 + 1
    OldStim1 = OldStim1 + 1
	If pos2 > 10 Then
	GoTo SelectPosition
	If OldStim1 > 10 Then
	GoTo SelectOld
	Else
	'NImg.Filename =c.GetAttrib("NImagen")
	'NImg.Draw
	NImg.X = "441"
    NImg.Y = "384"
'	RImg1.Filename = c.GetAttrib("RImagen1")
	'RImg1.Draw
	RImg1.X = "589"
	RImg1.Y = "384"
	c.SetAttrib "Location", "2"
	c.SetAttrib "PosOld", "1"
	Debug.Print c.GetAttrib("PosOld")
	End If
End If
End If


The problem is that the script does not work, the program displays the
three images. I do not know how to make the program ignored the image
should not be presented.

Can anyone help me?
