Setting OLEDB Connection String With Variables

I am trying to set the connection string in a connection manager at runtime. Here is what I have done:

1. Created a gv_DataSource, gv_Username and gv_Password

2. Created a ForEach Loop that reads DataSource, Username and password values from a variable (it is an For Each ADO loop Enumerator). The ADO recordset is read into by an Execute SQL task before the loop.

3. Mapped values from the recordset to variable in the ForEach loop's "Variable Mappings" page.

4. Used the variables in my Sybase OLEDB Connection Manager's "Expression" property, setting the "ConnectionString" property to:

"Data Source=" + @[User::gv_DataSource] + ";User ID=" + @[User::gv_Username] + " ;Password=" +
@[User::gv_Password] + ";Initial Catalog=blue;Provider=Sybase.ASEOLEDBProvider.2;Persist Security Info=True;"

5. I set the values in my database table for the connection-I set 2 connections for which I have Sybase OLEDB datasources setup.

When I run the package, I just get the first server's data twice, it doesn't set the second server's data during the second loop. I made sure the first one was working (i.e. the ConnectionString's property was being set by the data from the current variables) by setting the variables incorrectly in the variable properties page, and then running the package. So the first row of connection information is working, but the second loop around it doesn't seem to be working. I used a msgbox in a script task to show that the variables are mapping correctly in the loop, so it seems the second time around the connection information isn't taking from the variables.

What am I doing wrong here?

Thanks,
