Defining Variable problem

Question

Hi,

I have 2 variables defined in a code module as public which are used in the same 3 sub procedures. While the first variable is ok, when I debug, the second variables comes up "variable not defined"! Can anyone help? PS I'm a researcher using VB to design experiments and not a programmer!

Thanks

Post the code?

Also, I don't recall how much of a difference it makes, but you might consider changing (if it's in a module) public to global.

so:

global varname as whatever

Many thanks - I'll try global and post the code if it doesn't work!

Thanks again

Alright, let us know how it goes.

Sorry, it didn't work so here are the relevant parts of the code. I have included the global variabal declarations plus the three sub procedures: BuildExperiment; BuildExperimentTrial and Reset. The problem appears to lie in Reset where it accepts all the variables expect for colour1, 2....12.

You will realise from this that I am not a programmer but a researcher trying to write an experiment!!!

Again, your help is greatly appreciated.

CODE:

Option Explicit

'Array holding experiment details and results
Global ExperimentOrder(288, 20) As String

Global ExperimentMode As String ' Practice or Experiment
Global VisFieldVar As Integer
Global CurrentTrial As Integer
Global FileName As String

'Actual values
Const TotalETrials As Integer = 288 'total no of experimental trials
Const ValidETrial As Integer = 144 'no of trials for each valid condition (288/2)
Const EColourTrial As Integer = 24 'no of trials for each colour set (288/12)
Const EPositionTrial As Integer = 48 'no of trials in each position of visual field (288/6)
Const TotalPTriaGlobalGloballs As Integer = 12 'total no of practice trials
Const ValidPTrial As Integer = 6 'totalptrials / 2 conditions
Const PColourTrial As Integer = 1 'no of trials for each colour set (12/12)
Const PPositionTrial As Integer = 2 'no of trials in each position of visual field (12/6)

ok, I'm assuming this is VB6, if you want to send me the code in a zip file, I'll see what I can do with it.... I'm not seeing why there is a problem, since colourx through colourx is globally defined (I'm assuming they are globally defined in a code module). Anyway, send me the project and the files in a zip file, and I'll sift through it, and try to debug it for you.

Hi,

Thanks for this - I have attached the whole project for you and yes, it's VB6.

I think I've managed to attach the file - let me know if I messed it up!

The last do of buildexperimenttrial sub requires your attention, and is commented. The others that I could find have been fixed and commented.... let me know how it turns out....

By The Way, The only changes I made where in the module.

Thanks for all that. I will make VERY sure in future that I check and recheck my variables! However, as you are being so helpful I wonder if you would help me with timing. I have written a sub procedure to do this as doing it on each form only works for one trial but this doesn't work at all. None of the textbooks seem to address the problem of timing forms each time they show.

Any ideas? I have attached a new zip of my coding which I have changed plus a flow chart of the experimental procedure (order of forms).

Thanks again in anticipation for your help.
