is null or not an object error depending on order of code

[rmurgia]

I need to determine which key was pressed, then do some error checking and finally determine which screen to load. The following code was used to determine which screen was pressed:

var strkp = document.pressed;

The screen was set after doing some error checking and determining which screen to load:
document.frmMASMaint_02.action = "frmMASMaint_02.asp";

When the above code is placed after document.pressed, it works. When there is other code added, such as some debuging code like:

document.write(strkp);

The 2nd line errrors out with:

Error: document.frmMASMaint_02 is null or not an object.

It appears that somehow the frmMASMaint_02 is being removed from memory.

Does anyone have any idea if the DOM object has some quirks which would make this happen. Any ideas would be greatly apreciated.

you cannot use

document.write()

with a loaded document ... this will destroy the current dom-tree ... make an alert or use a div and set its innerHTML instead ...
