Trailing spaces are often removed from data. In your case, the easiest thing to do will be to use what is called the "hard space" character instead of a "real" space. This is key code ALT+0160. For all intent and purposes, it looks like a space and will print as a space, but since it is not technically the space (0032) character, it will not be trimmed from your projects. Just open the quotes, turn off the NUMLOCK and hold down the ALT key and type 0160 and then release the ALT key. This will add the hard space into your string. Then if you are like me, you will have to remember to turn the NUMLOCK back on.

I'm not sure how this will post into this message, but the example above is using hard space characters.
