Changing Doctype from Strict to Transitional stops script

[sarmadys]

Hello,

1- I have a Tabs list (Services/Solutions/Internal...) in below website which has been done using Javascript.

http://reorex.com/tt/en/indexa.php

Now if I change the Doctype from Strict to Transitional the javascript ceases to work correctly (and I was not able to find why).

See here:

2- I need the Transitional doctype because my language menu does not work with Strict!!! and I guess fixing the Javascript might be easier than that.

What is the problem? What should I do to avoid such problems? (I guess I prefer strict type XML documents).

Thank you very much for your help.

Regards

I put both those links through the w3c validator and it tells you exactly what the problems are.

Validating your code often solves a lot of problems

Thanks.

Validating second link ( http://reorex.com/tt/en/ ) did not fix the problem (you can see the page passes the test now).

Validating the first link ( http://reorex.com/tt/en/indexa.php ) crippled the working script and I revived it to the previous version (in case someone wants to see the working script).

It would be better to fix the language menu to work with HTML 4 rather than trying to patch the JavaScript to work with HTML 3.2
