onLoad, and onChange

[schroom]

I have the following code as an onChange, and would like to also have it as onLoad
as onChange it is:
onChange="return (isAgeAtRetirement(this, termDtYr, termDtMn, termDtDy)

and trying as onLoad:
... isAgeAtRetirement(termDtYr, termDtMn, termDtDy, 20000);">

which gives the following error: termDtYr is undefined

Why is this and how would I fix it??

We need to look at the code to see why this might happen...can you post a URL??
BTW, why would you want to call the same script as onLoad and onChange?? I have not failed; I merely found 100,000 different ways of not succeding...
