A quick look shows that you missed the "t" in all of your Alerts. Did
you cut / paste the original line with spelling error or is there a
Javascript command called "aler"?

<snip>

The first step if resolving an error is to read the error message
generated for the error (in IE, for example, you go into Tools->Internet
Options->Advanced and disable script debugging and enable the showing of
error messages for every script error and then re-run the script. The
error report dialog then pops up every time there is an error (and it is
always the first error reported that needs to be fixed first). The
wording of error messages is not always as obvious (or helpful) as they
could be, but they are machine generated and completely consistent in
their cause and effect relationships.

(Note: The inappropriate use of try-catch in javascript can act to
conceal and suppress errors. The javascript try-catch mechanism is
particularly ill-suited to error handling because it can only catch all
exceptions and there is virtually no standardised information to tell
you which exception has been caught. It cannot be avoided for tasks like
instantiating ActiveX objects but should otherwise be avoided in favour
of testing the viability of actions prior to taking them.)
