I used Google and found some references for integer in Java.
But "int" not only does not work, it also prevents reading X and Y coordinates of the mouse.
What i would like to do:
1) Get X and Y mouse coordinates into a variable that i can do real math on.
So far, i can do math on the values "read" and that result goes into a "variable" that is useful *only* for display.
If i try "int" in that math, the values are then zero for everything - even those where i do no calculation.
2) Use the calculated integer values as an index to a table or array.
It is acceptable to use an HTML "table" as the source for the lookup; W(CalcFromX) and P(CalcFromX) would be the resulting values to be displayed on the screen somewhere.

Can this be done, and eXactly how?

Here is the code i have so far:

This code *used to* work, showing a calculated year in the first 2 boxes; the width

I have no idea as to why they no longer work.
I added "Z value" and *that* works (!!). Go figure.

Yeah,
this is JavaScript,
which basically has nothing to do with Java...
I believe there is some Object Orientation in it,
but not as advanced as Java's.
I'd recommend you go to the comp.lang.javascript group instead, or a similar one...
Thanks.
