Update of record - error

I am trying to run the following query and am receiving an error:

UPDATE TI_COMPANY_LISTING SET BANNERURL = Buildertrends_100x150.gif WHERE COMPANY_ID=2358

ERROR:
Msg 4104, Level 16, State 1, Line 1
The multi-part identifier "Buildertrends_100x150.gif" could not be bound.

I am not familiar with this error, it is the first time I have received it.

Thanks.

re: Update of record - error

can you re-check the way of passing parameter?
or can you post sample of your code?
