Buffer Exchange Error

[Nord3r]

Evening everyone,

New member and first time poster here so apologies if this is in the wrong section.

Im currently building a producing instructions for a model and have use a buffer exchange command to show the placement of a tile in the main build.

Now Ive followed the information from Holly-wood.it and the working with pub google site but I still have an issue.

The 'hovering' part appears with the arrow in the correct location but on the next step it recounts the piece in the PLI so you end up with a extra piece. Is it something simple that I've missed or arranged incorrectly ? The code looks correct but Im not sure.

Here is the code:

Just to make clear to anyone reading this and willing to help out, the problem has already been solved on the LDraw forums

Legoliintie, it has indeed! Thanks for copying the link over. That was me asking on Ldraw and I meant to post the answer here but got distracted
