/* The first <<linkreplace>> macro */
<span id="truther"><<linkreplace "Tell the truth.">>"Yavin 4," you murmur.<<replace "#liar">><</replace>><</linkreplace>></span>
/* The second <<linkreplace>> macro */
<span id="liar"><<linkreplace "Lie.">>"Dantooine," you murmur. "They're on Dantooine."<<replace "#truther">><</replace>><</linkreplace>></span>
There may be a better way, but here's how I do it. Put a span around each thing you want to remove -- make sure their IDs are unique and easy to remember. Then, replace the other ID with nothing --- in effect, deleting it. (You could also replace it with the same text, but not within a linkreplace macro, so that the player can still see what they could have chosen prior to this point --- ie, <<replace "#truther">>Lie.<</replace>>)
Also....... eyes emoji @ all these Star Wars references... I'm intrigued.
edit: As an aside comment to my answer on a previous post, I still highly recommend installing that add-on pack. It has so many useful macros that I find it invaluable in every story.
