You can move the following if-block up in the function:
for (i=0; !x && i < d.forms.length; i++) {
x = d.forms[i][n];
}
This is, however, the wrong solution - rather than using this general
'getele' function which tries to find something somewhere in the document
with the appropriate element type/name attribute/id attribute, it would be
better to search only within the specific namespace required (form field
name, in this case).
