html element question (getElementById)

[Manny Mo]

when i try to store a .getElementById (), i notice it never stores it properly. for instance i could have this code..

b = document.getElementById('buttonName');

but when then i never get any results when i try to actually use b as an object, such as..

var x = b.offsetLeft;

it works for me, maybe you invoke the call too early?
