Funktion med variabel

Hvorfor kan jeg ikke sætte strA til at være "A1","A2","A3" osv.?..

Det er et felt i en formular jeg skal have aflæst.

function Substitute(strImg){
var strA = document.getElementByName('A'+strImg);
document.images['Img'+strImg].src="img/colors/"+document['form'+strImg].strA.value+".gif";
}

det du gør med sætningen
var strA = document.getElementByName('A'+strImg);
er at gøre strA til en pegepind til det html-element der har id "A"+strimg

for at sætte strA til det navn skriver du:
var strA = "A" + strImg;

men under alle omstændigheder vil adressen
document['form'+strImg].strA.value+".gif";
gå galt. du kan ikke umiddelbart bruge variabler når du sammensætter en .-adresse.
det skal være:
document['form'+strImg].elements[strA].value+".gif";
så strA bruges til at slå op i formens array af elementer.

Det virker fint i den første formular, men de to efterfølgende virker det ikke i..!?
Hvis den ".elements" virker så burde den jo henvise til "A2" og "A3", men den siger bare "'document[...].elements' is not an object."..
