Check/Uncheck problem with checkbox

Hi,

Good day to all.

I experienced an issue with the check/uncheck module.

The java code below works fine if there are more than one “field”.

If there’s only one field it will show some error as “0.checked is null or not an object”

Can anyone help?

Regards,
Jack

<!–
var checkflag = “false”;

function check(field) {
if (field[0].checked) {
for (i = 0; i < field.length; i++)
{field[i].checked = false;}
checkflag = “true”;
return “Uncheck All”;
}
else {
for (i = 0; i < field.length; i++)
{field[i].checked = true; }
checkflag = “false”;
return “Check All”;
}
}
