HEC-HMS warnings "no flow"

[SavariaEnviro]

Im having some trouble running HEC-HMS, im new at this and am playing around with it, but I seem to be getting the following errors,

WARNING 40802: Total inflow to reach "Reach-2" is zero.

and i dont know where to look to solve this problem, I have 2 subbasins with the data entered the same way with a reach for each that join at a junction, but one returns me a no flow result, what gives?

Start with Edit -> Steady Flow Data

Is there a flow entered for the upstream most river station of "Reach 2" ..?

beej - I think its HMS not RAS. Make sure your routing reach is linked and that your basin produces runoff. Sounds like you need to check your coding.

gbam, is right, it's HMS. I fixed the problem, the curve number used was not the right one and it was too low so no runoff resulted.

Thanks

Brainfart, my bad. Been staring at RAS for the last week and a half and had RAS on the brain.
