Hyperlink in SSRS shows 2 & field name while using it with Sharepoint

While using the GoTo URL link in SSRS to open a sharepoint list like below

="http://devserver:1882/Lists/Regions/DispForm.aspx?ID=25

I used the below settings in GoTo URL option in Action tab

="http://devserver:1882/Lists/Regions/DispForm.aspx?ID="&Fields!Region_ID.Value

but this would bring up wrong results i,e

="http://devserver:1882/Lists/Regions/DispForm.aspx?ID=25&ID=25

We can resolve this issue by adding extra / before your.aspx page

="http://devserver:1882/Lists/Regions//DispForm.aspx?ID="&Fields!Region_ID.Value
