var lala = document.date.lpag.value
if (lala == "G" ) { document.date.car.options[document.date.car.selectedIndex].value= "G" }

You may have to run a loop to find when car.options.value=='G'
then, car.selectedIndex=i

document.date.car.options[document.date.car.selectedIndex].value

i think you are trying to use options (an array variable) as an object of the "car" element. this won't work as it is logically incorrect. if the list box element can be directly accessed (i'm assuming it's document.date.car) then document.date.car.value can be set to the value of the option element and the value of the listbox will change accordingly.
