How can I include text in GS?

[mvlcek]

If I create 2 components and I inserted this 2 component in the same page (one at the beginning of the page ad the 2nd at the end of the page) only one is displayed. Why?

Just tested it (two times the same component with different arguments plus another component on one page) - works for me!
Maybe you have a blank between { and % or you use the wrong name - see components page, gray code example for correct name.
