Error 40 whilst setting data source

Hi guys,

I am trying to create a dynamic connection string to a remote machine. Initially I used the wizard to create a fixed connection, which created Data Source= (changed from original);Initial Catalog=Testmaster I opted to use the windows authentication option. All was well and the report linked to it returns data.

Now i'm trying to link the data source to a parameter (textbox) and im getting the Error40 my current string is......

="Data Source=" + Parameters!Server.Value + " Catalog=Testmaster Integrated Security = SSPI "

I cannot figure out where I have gone wrong here.

Could it be due to wrong connection string?
Instead of
="Data Source=" + Parameters!Server.Value + " Catalog=Testmaster Integrated Security = SSPI "

Open in new window

="Data Source=" + Parameters!Server.Value + ";Initial Catalog=Testmaster; Integrated Security = SSPI"

Open in new window

Yes this will be due to what Duy Pham explained because Error40 means No sql server\Instance name found.
