Hi,

I am trying to re-programme a VB task and I need to make the following addition:
The task involves the use of 2 rating scales. I want the participant to make their rating on the first scale and then, once the second scale comes up (after the participant is given additional information), I want for the scale to appear with the last rating as the starting point.

e.g..
If this is scale 1 as it appears

------------------------------X---------------------------------

and the participant mvoes the X using the keypad to here on the first rating:

----X-----------------------------------------------------------

I want for whenthe next scale comes, the code not to start with the X in the centre, but instead to start at the point where the participant last rated (in the first scale)

I am trying to measure the difference in the ratings (of happiness) before and after a certain event.
This is how the relevant (I think!) area of the trial code is looking

'(9)Rate result
'
If Me.bRateObtainedOutcome Then
Me.iHappinessStartTime = timeGetTime
Me.fHappinessRating = doRating(Me.m_OutcomeRating)

Me.iHappinessRatingTime = timeGetTime


'(11) Rate regret
'
If Me.bRateAfterBothOutcomes Then
Me.iRegretStartTime = timeGetTime
Me.fRegretRating = doRating(Me.m_FinalRating)
Me.iRegretRatingTime = timeGetTime
End If

Can anyone help me! I gather that it's something to do with creating a "remember" clause after the first rating or something like that...

I'm not sure where you're getting lost. It sounds very simple. You create a global variable (or a static local variable) and place the value in that variable. Then, when you display the second scale, you take the value from the global variable and use it.

Private SavedHappiness as integer = 0

'(9)Rate result
'
If Me.bRateObtainedOutcome Then
Me.iHappinessStartTime = timeGetTime

Me.fHappinessRating = doRating(Me.m_OutcomeRating)
SavedHappiness = me.fHappinessRating ' save the happiness rating for later use.

Me.iHappinessRatingTime = timeGetTime

'(11) Rate regret
'
If Me.bRateAfterBothOutcomes Then
Me.iRegretStartTime = timeGetTime

' I'm not sure what all this means. The final rating could be set to the saved happiness if this is what is called for the user to perform the rating.
Me.m_FinalRating = SavedHappiness

Me.fRegretRating = doRating(Me.m_FinalRating)
Me.iRegretRatingTime = timeGetTime
End If

thanks! But I'm still running into difficulty- something to do with integer vs double settings in the code I think.

Private SavedHappiness As Integer = 0


'(9)Rate result
'

If Me.bRateObtainedOutcome Then
Me.iHappinessStartTime = timeGetTime
Me.fHappinessRating = doRating(Me.m_OutcomeRating)
SavedHappiness = CInt(Me.fHappinessRating) 'I had to convert to Integer to get the error message gone)
Me.iHappinessRatingTime = timeGetTime
'

'(11) Rate regret

If Me.bRateAfterBothOutcomes Then
Me.iRegretStartTime = timeGetTime
Me.m_FinalRating = SavedHappiness

'error message here reads: Value of type 'Integer' cannot be converted to 'GameTask.Trial.Rating'.

Me.fRegretRating = doRating(Me.m_FinalRating)
Me.iRegretRatingTime = timeGetTime
End If

I've tried doing it all in double, but the same thing keeps happening- except it says 'double' in the above error instead of integer

I am a VB novice- in case not already obvious! Any help is MUCH appreciated!

What values does "GameTask.Trial.Rating" hold? I guess what I'm asking is what is its type. Until I understand that, I can't help you with converting something to that.

You can declare SavedHappiness as type "double". Then you would use "CDBL()" to convert Me.fHappinessRating to SavedHappiness.

Types are sometimes confusing to novices, but they're very important to programmers.

I just got it to work!
Thanks a million for your help!
