Playback Multiple Tracks

New to all this (still) WindowsXP, Tascam US1800, Cubase 5LE.
How do i playback multiple tracs? I have 2, piano on trac1, strings on trac2.
No matter what i do i cqn only hear the piano on trac1
I’m sure there’s something on trac2 cuz i can find the wave file and play it.
I’m sure monitoring isn’t enabled as well.
Thanks for any info…

What’s the output of the problem track set to? Screenshot of the Project window with the Inspector of the problem track showing.

set to the same stereo out channel as trac1

also,not sure how to attach something, the forum didn’t like the .BMP file i tried to attach…
