I have a form that has options on it, I cannot seem to get the progress bar to reset properly. if i open the form and select a client and press the red button the progress is fine, it stops when complete with a message, if i now go on to select another client and press the red button again the progress bar doesn't go back to the beginning.

y grabs the count of records

I am just not seeing whats wrong.

you need to reset the .Value property when you restart your process. You should set to the value of the .Minimum property:
ProgressBar1.Value= ProgressBar1.Minimum
