Copying Data From Another DB On Server Problem

What iam trying to do is put the table name from one db into a variable and another one into another variable and pass them into my statement basicaly trying to bulk copy data from one table in a db and insert it into another db on the same server based on a condition

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[ClientComment]')
and OBJECTPROPERTY(id, N'IsUserTable') = 1)

Declare @BDFR varchar(20), @BDTO varchar(20), @EQID varchar(20)
set @BDFR = 'Commander' + '.dbo.' + 'ClientComment'
set @BDTO = 'Test_Commander' + '.dbo.' + 'ClientComment'
set @EQID = '80_300_005'
insert into @BDTO
select * from @BDFR where Eqid = @EQID
