RoR,
Line 68 is:
var iCount = arElements.length
This fails because arElements is not defined. At this point in time all
of the expected output has already appeared, so you don't notice the
failure (which prematurely terminates the script).
BUT, when you have an outer script that calls the inner one twice, the
failure of the first call also terminates the outer script and the
second call is never made.
Remove the comment delimiters from the line (2 lines up):
// var arElements = document.getElementsByTagName(sType)
and it will work.
In Firefox:
Tools
Error console
will show you any JavaScript parsing or execution errors. This is where
to start looking for this sort of thing.
