How to "have"/"haul" something into flight

[Zolos1082]

I am doing the mission haul TR-5 "flea" soild fuel booster onto flight above kerbin 

Requirements 

Have tr-5 flea soild fuel booster 

Kerbin

Flying

Alt: 32,000m to 37,000m

Spd:330.0m/s to 470.0m/s

It will say I have all the requirements besides the "Have tr-5 flea soild fuel booster" one. I've tried attaching it in what seems to be every way possible but I guess I'm missing something. Please help

I usually skip these contracts, because they seem to be a little finicky and/or won’t trigger until some unknown specific action happens (I had a “haul a TD-12 decoupler on escape orbit out of Kerbin” mission, it didn’t trigger until I decoupled the stage, once I confirmed my free-return trajectory, right before reentry).

 

That said, I don’t think you can use the booster until after you’ve met the mission criteria. Or it’s a bug in the contract...
