Participants=?ISO-8859-1?Q?=B4_?=response via space key

[Claudia]

Hi again,

I am clearly doing something wrong since, although I believe I
followed your (and the manual) instructions, I keep getting the same
error window. Could you please look at it and let me know if it tells
you something? I am copy-pasting below the section containing the
'bug' - The last line seems to be the critical one.
Thank you very much,
Claudia

Sub PracticeProc_Run(c as Context)

	Fixation.Run

	Blank.Run

	PrimePractice.Text = c.GetAttrib("PrimePractice")
	PrimePractice.Run

	Blank1.Run

	Stimulus.ActiveState = c.GetAttrib("Stimulus")
	Stimulus.Run

	ResponseTrial.InputMasks.Reset

	If Keyboard.GetState() = ebStateOpen Then
		ResponseTrialEchoClients.RemoveAll
		ResponseTrial.InputMasks.Add Keyboard.CreateInputMask("{SPACE}",
c.GetAttrib("CorrectAnswer"), CLng(ResponseTrial.Duration), CLng("1"),
ebEndResponseActionNone, CLogical("Yes"), "", "", "ResponseMode:All
ProcessBackspace:Yes")
