Use of Summation to calculate block accuracy and repeat block or move on

[Val Karuzis]

Hello,

I have a script that is supposed to move on if participants get 80% or more correct on the practice trials.  However, one can get 80% or more correct and it won't move on.  The issue seems to be that the summation object in the in-lines is not updating.

Here is how it's set up:

In the user script:

Dim VAccuracy As Summation

Earlier in the procedure (right before the practice list):

Set VAccuracy = New Summation

After the object and feedback:

'Debug.Print VerbLearning.ACC

VAccuracy.AddObservation CDbl(c.GetAttrib("VerbLearning.ACC")

'Debug.Print VAccuracy.Mean

Unfortunately, the debugging is showing me that, although accuracies are 1, the VAccuracy.Mean command is always 0 (and never 1).  I don't *think* it could be a decimal point issue, because even an accurate response on the first trial leads to a VAccuracy.Mean value of 0.

Any ideas on why it is not updating?  

Thanks so much for your help,

Val

Sorry, all!  I had to take out the c.GetAttrib, since the attribute wasn't updating before the end of the procedure.  So that line worked with:

VAccuracy.AddObservation CDbl(VerbLearning.ACC)

Thanks to Susan Campbell for the amazingly quick fix.

Glad you got it sorted. Can't resist commenting
on one thing, seems odd that you would cast .ACC
to a Double there. .ACC is always either "0" or
"1" and so evaluates to an ordinary Integer. If
I had to cast it I would use CInt(), although in
this case E-Basic will do automatic casting, so I would simplify this to just

VAccuracy.AddObservation VerbLearning.ACC
