Date Validation upon field exit 1

[TidewaterJoe]

I am able to validate the format of a date - when the form is submitted, but not when the date field is exited. I now need to know that date when the field is exited so that I can immediately update another date field. For example, if startdate = 01-01-2006, I need to immediately update the stopdate by adding, say, 3 years, to that initial startdate.

I know how to do this with list boxes (if option A is selected in field 1, then the options for fields 2-5 default to some value). But am brain dead on this similar date problem.

Thanks in advance for any help.

onBlur() is the function to capture the event of the focus moving off of a particular field.
