Why msn and yahoo not crawl my pages

[tamnle123]

Please helps.
I submited my sitemap on google, yahoo and msn long time ago. Look like google index some of my pages OK but yahoo and MSN are taking forever. At some point msn index a lot of pages but now they start deleting and there is only couple pages left on msn, yahoo only have 4 pages and google has over 150 pages.
I am using subdomain and I submit both sitemap here

Please advice.
Thanks You

Hi,

I'd remove the scripts from the root page, //window.location =
and document.location.href from the coupon and raise every thing up to root directory.

VERY confusing for the bots I'm surprised Google indexes them at all, i doubt that you'll ever rank well using that!
