Prohibit field modfication based on calculation?th

[wintergreen]

I kind of feel like this is something I should know, but is there a way to prevent a user modifying a field based on the value of another field?

For instance, say I have two fields, "name" and "nameLock" and I only want to be able to modify "name" if "nameLock" is empty.
