connect to two different database hosts

Hi everyone,
Im using last version of Chronoforms at J! 2.5
is possible make connection to two different hosts? (In advanced mode use action DBSave two times?)

In first action DB Save with local db - success

Second action DB Save with remote db is not working
like host i used: db51.remoteserver.com:3309 Is it correctly?
(in simple php script connection works, but no in Chronoforms.)

Hi kubo,

Try with just db51.remoteserver.com without the port number. The remote database has to be accessible from the Joomla! server.
