Linked site loads all deformed.....

[Jaske]

I recently linked an OsCommerce store from my vB/vBa and when you click the "store" link in the header/navbar and go to the page the page is all out of order....boxes are too far to the left or right and the page is all screwed up....however when I type the url to the store/site the page loads perfectly....any ideas on why this might happen? I can't think of why the link from my vB/vBa would make the page get messed up....please help! thanks in advance.
