In an existing, tested and working program, I have a form entry that
simplifies to...

<input type="button" value=" Set Amplitude "
onclick="setAmp litude (this.form)">
One of the things the setAmplitude function does is calculate a p1s
value and then does a...
form.fp1s.value = p1s ;
This seems to work fine. I wanted to add a new feature to the program
by adding a new button of
<input type="button" value="Improve? " onclick="imProv eX
(this.form)">
An initial function for imProveX was...
function imProveX (form) { setAmplitude (this.form) ;
} ;
This should be doing the same thing the other button does, except from
within a new proc instead of a button click. Instaad, an error of ...
'fp1s' is null or not an object
gets returned.
What am I doing wrong?

Depends on what version of java you have, and what you are developing
scripts under, and their co-compatibilities .

here this refers to the imProveX function and there is no form
property for function. pass the argument to setAmplitude function and
all should be fine.
function imProveX (form) { setAmplitude (form) ;

Could also relate to the runtime engine you are trying to run it
under.

The this above refers to the function and as such has no property named
"form". If you want to pass it, simply pass the parameter form.
