How to set geographic transformation in a model?

All my data is stored in WGS84 and I am attempting to reproject it to various NAD83 state plane zones using Model Builder.

My model iterates through the data and sets the output projection.

However, how do I set the geographic transformation?  It is required when going from WGS84 to NAD83 and it is blanked out because the output projection is set to a variable (i.e. %Output Projection%).

As a result, the Project tool is whited out and won't run.

In the script tool that determines the state plane zone, I've tried setting the model environment using
arcpy.env.geographicTransformations = "WGS_1984(ITRF00)_To_NAD_1983"

but that doesn't work.

Any ideas?

If you expose both parameters they should both be available.

Please attach your model using the "paper clip" tool.
