In your formula: sqrt(tU*tU+tV*tV)-sqrt(bU*bU+bV*bV) are tU and bU different variables or are t and b constants? Are you trying to do a layer shear? If so, how are you selecting the layers? Have you tried the formula Grids->Layer Wind Shear? That will allow you to select the layers, and then select the the U, V and Z components. You'll need Z to calculate dz between the layers. If you just want a magnitude of the speed difference, it might take a little Jython to do the appropriate slicing.
