NIST The "substringData(offset,count)" method raises an INDEX_SIZE_ERR DOMException if the specified offset is greater than the number of characters in the string. Retrieve the character data of the last child of the first employee and invoke its "substringData(offset,count) method with offset=40 and count=3. It should raise the desired exception since the offsets value is greater than the length. Mary Brady 2001-08-17
