tuplet problems; dialog box terminology

[Barbie-liever]

Alex, I don't know what I'm doing wrong. I have 3 quarter notes that need to become a tuplet in the space of 1 quarter not beat. I clicked the tuplet tool, then clicked the first and last of my 3 notes. Nothing. I tried again, this time holding down the shift key. Nothing.

 

I had it work on another project, but when I tried to paste that measure elsewhere, even within the same song, the bracket didn'tt appear. I tried right clicking the tuplet to play with the dialog options, but I don't understand the terminology. Some examples would halp. Even playing with those terms (bracket above, below, using eighth notes, 16ths, etc.), nothing changed.

 

Would you consider posting a tutorial on youtube?
