Visual Studio 2005. VB

I am going through the tutorials and I cannot build the website because in the code behind the "Imports InfoSoftGlobal" has a green squiggly line under it and says "namespace or type specified in the 'imports InfosoftGlobal' does not contain any public member or cannot be found.
Also, the code:
    Return FusionCharts.RenderChart("../FusionCharts/FCF_Pie3D.swf", "", strXML, "FactorySum", "650", "450", False, False)
has a squiggly line stating "name FusionCharts is not declared"

I have followed the tutorial properly and have FusionCharts.dll in the bin directory.

I can rightclick on the pages and view in browser and the pages work but I cannot build beause of the errors mentioned above.

Thanks for your help,

Steve.
