Import *.dbf Dynamically

Hi, there;

I am doing a SSIS project, my target is:

I have a source folder which have some *.dbf files (the number of
files will change as time goes on) exported from another application. I want my SSIS package to load data from these dbf
files in the source folder to my SQL2005 database no mather how many
dbf files will be.If the destination table already exists in the database,
the logic logic will do update (delete and import again), if not, create a new table on th fly and then
pump the data.



What I did here is that I have a foreach loop container which contains Script
task, Execute SQL task and a data flow. The Foreach container now can
connect to the *.dbf files successfully, the Script task can read
schema information from each dbf file and create script "Create table ...."
successfully and Execute SQL task can create table in my new empty
database successfully! But I have problem in the data flow task: my OLEDB Source points to the dbf file folder and set Data Access mode to "Table name or view name variable",but when I set Variable Name to a package level variable ("tableName"), I get error: Error at Data Flow Task_Pumping data from Admar [OLE DB Source [2737]]: A destination table name has not been provided.
Exception from HRESULT: 0xC0202042 (Microsoft.SqlServer.DTSPipelineWrap)

Does anybody know what to do to create table and pumping data on the fly? (Using variable as table name)

Big Thanks here.
