Deselecting or "hiding" option when selected

[shaggai]

Planning on something for an upcoming release and having problems in trying to make something look nice.

You have an option, say flamethrower and once that choice is chosen a second option is made available "Mastercraft this weapon" which shows just underneath it (via chained option with Init_Synch). When this option is selected the name of the original weapon is change via the Eval to "Mastercrafted Flamerthower." All well and good so far...

Once that is done I would like to have AB remove the "Mastercraft this weapon" line and that is where the problems occur. The usual problem in trying numerous ways of removing it all come up with the red type and illegal option, and some experimentation also yields infinite looping!?!

Once a player chooses an option is it pretty much a one way choice?
