C# Open,Close,Hide custom forms

I had to go a different route.  I was assuming that each instruction had a new experiment page, that it would be appropriate to pass in the settings as parameters. The parameters were causing the form to load before the Instructions were issued.

Now I run a timer to count down the response time the user has.

Form_Enter()

while(numbRunTimes <10)
{
     RunExperiment();
}

RunExperiment()
{
numbRunTimes++;
xTimer.Start();
right = evaluateResponse();
reinforce = evaluateReinforce();
}


The idea is that when the form loads, the timer starts. After 5 seconds the user response is evaluated(did they press spacebar or not). We keep a running total of the right answers. Display updated values.
After the display is updated, I want it to wait 3 seconds before starting another 5 second wait for them to select their next response.

I continue to call the RunExperiment() until it has been run 10 times.

When I run it outside of debug mode, it  shows up like it's already finished the experiment, even though the users hasn't had time to test it.


private void RunExperiment()
        {
            exp.shownCues++;
            StopTime = 50000;
            xTimer.Start();
            this.lblTestNumber.Text = exp.shownCues.ToString() + "/" + C_TEST.ToString();
            right = exp.IsSpaceCorrect(input);
            if (right)
            {
                reinforce = exp.IsResponseReinforced();
               
                this.lblCue.Hide();
                this.lblScreen.ForeColor = System.Drawing.Color.Green;
                this.lblScreen.Text = "OOO";
                this.lblScreen.Show();

                if (reinforce)
                {
                    reward = reward + .25;
                    this.lblVal.Text = "$" + reward.ToString();
                }
                ResetCue();
            }
            else
            {
                this.lblCue.Hide();
                this.lblScreen.ForeColor = System.Drawing.Color.Red;
                this.lblScreen.Text = "XXX";
                this.lblScreen.Show();
                ResetCue();
            }
        }

        private void ResetCue()
        {
            Wait();
            this.lblScreen.Hide();
            this.lblCue.Show();
        }

        private void Wait()
        {
            StartTime = 0;
            StopTime = 30000;
            xTimer.Start();
        }
        private void xTimer_Tick(object sender, System.EventArgs e)
        {

            while(StartTime< StopTime)
            {
                StartTime++;
            }
            xTimer.Stop();
            RunExperiment();
        }
private void Cue_Enter(object sender, EventArgs e)
        {
           while (exp.shownCues < C_TEST)
           {
               RunExperiment();
           }
           FinalWait();
        }


Any ideas why it would skip the timers?
