I've looked over your code and I can't see anything specifically wrong. Can you post the error message you're getting? That might help. As a side note, you may want to replace pf['InitialTime'] on line 35 with data.pf['InitialTime']. The pf is global within your script, but if you those field functions in other files you will get an error because the function will not know about pf.

Dear all,

I'm trying to plot the projection of a variable defined in a rather involved
way, namely through an IF statement. I can use this variable for many
computations and I can plot slices of it, but somehow it does not work with
projections. I attach an example script which isolates the problem. I guess
it can run on any standard cosmological output of Enzo (v. 1.0; I haven't
worked with Enzo 1.5 yet). As I told you, if I change the
pc.add_projection(... at line 65 with
pc.add_slice(...
everything works well.
I'm using YT 1.6, and because of problems in my machine I cannot upgrade to
1.6.1 until next week, so I don't know if this issue has been already fixed
by chance.
Looking forward to your suggestions,
Cheers,

Luigi
