Detail report is blank after deploying

Hello all, I have an SSRS report that runs good in Visual Studio but after it's deployed to our intranet, the detail portion of the report is blank and only showing the headers. However, the summary detail portion does display. Ther are other reports that work fine on the intranet and only this one does not work. I've try to re-deploy the report but it keep producing the same result. Any help will be greatly appreciated. I'm running Visual Studio and the intranet with the same user login account. This is in SQL 2005.
