Obejct Doesn't Support This Method Or Property Error

i had deploy my MSChart and MSFlexGrid control in my web server... the location of the cab file in the web server is
c:\inetpub\wwwroot\projek1\cabfile\MSCHRT20.cab

then in the codebase property of the control inside my project, i specify it to "http://serverName/projek1/cabFile/MSCHRT20.cab"

but when i try to run it on a client side, it gave me the "Object doesn't support this property or method".. is it means that the control is not downloaded and installed at the client computer? so what's wrong with my code?

thanks in advance for help...

good days....
