There is a DEBUG menu in SSMS, but you'll likely need to be on the server to be able to debug, so if it is a remote access, it's probably not gonna be set up for it. That debug option will allow you to execute code, and step into your trigger and debug it in that manner (as you'd debug most any other code).

If not having access to the debug menu/function, you'll have to debug "manually":

First ensure your trigger is running correctly by inserting the input of the trigger into a debug table. Then you can verify that its called correctly. Then you can debug the query of the trigger as you would any other sql query, using the values from the debug table.
