Math & Science ⇒ Integer symbol

[james121515]

Hi guys,

I'm having a problem getting the integer symbol (the Z) to work in WinEdt. When I try to use either \mathds{Z} or \mathbb{Z}, when the code runs it stops there and says "undefined control sequence". Yet all of the other symbols work just fine. Any tips?

Thanks,
James

Are you loading the amsfonts package? (The amssymb package would also do, since it automatically loads amsfonts). If that's not the problem, please let us see your code.
