Ah dammit. I forgot about your question.
Sorry for the delay,though.

1. Paste blue brick tiles where you want the invisible tiles to appear later.
2. Copy/paste your code into word, notepad, ...(just some place you are able to edit your code at.)
3. In the tile section, first section, you can find the tiles in your code.
4. Search for 3d not 3D and replace it by 7^ to replace a blue brick with an invisible tile. (Pretty much only ID changing.)
5. Now copy/paste your code back into the designer and you should find an invisible tile where a blue brick has been before.
6. To get more invisible tiles, you simply need to replace more often 3d by 7^.

Note: Be careful. If you used blue bricks in your level before it may happen that you turn those into invisible tiles too. Depending on the coordinate stuff I don't think I should further explain right now.

2.Note: If you replace 3d by 12 you get a white grid tile, 13 a white background grid tile and for '' not using " (meaning you shall not use caps of 2, but the other one for these.)you should get a dark background grid tile.

Hope it helped.

OK.So wait for my level. Thanks!!

Just leaving a quick note- every tile has an ID so don't feel like you have to use the blue bricks to replace them with. However it's probably the most well known tile ID so I'd say it's the easiest one.
