Thank you chestertb, steelersfan88 and kor for trying to help me. It was much appreciated.
In hindsight, much to my chagrin, I may not have reported what turned out to be a critical piece of information.
Using FrontPage 2002
Form Name: registration
Field name: password
Specifying constraints within FP2002 on the field.
Another point which may be of interest. If you use, as was suggested, a function within onSubmit instead of onClick (on the Submit button) it MUST be called FrontPage_Form1_Validator
Finally while there may be other ways of doing it, because I wanted to add another check above those provided by FP validation I did the following:
1) Within the Form Field properties I set all my validation.
2) I published the page.
4) I then removed all the field vaildations with FP, pasted in the code it had generated when the validations were in place, added my additional code and then republished the page.
If any of this does not make sense or you want additional explanations please feel free to say so
