How to Use Variable in Sharepoint List source SiteURL property ?

Hi All,

Am using a Shrepoint List as a source in my DFT, i had provided SiteListName,SiteListViewName and SiteURL and it is working fine.

The siteurl is project specific one. I have some n number of databases. So i have used a Forloop container to loop through it. Am assigning the ProjectURL to a variable and using that variable in Sharepoint List source for SiteURL property. But am not able to do that it is throwing error to specify URL.

Am not able to assign variable to SiteURL property.

Hope i have explained clearly, if not plz ask.

Thanks,

Amit
