I'm using the modular station blueprints from viewtopic.php?f=194&t=47773, specifically the Fluid-Loader-Full and Fluid-Unloader-Full. The loading station's tanks are full, and I have two L-CCCC-L fluid trains waiting at the depot. LTN isn't sending either of them to the station. What am I doing wrong?

I figured it out, i was sending a positive 300k oil signal to the unloading station instead of a negative one.
