I don't know what you're doing, but:
Code:
frame:SetPoint("BOTTOM", otherFrame or UIParent, "CENTER", 0, 100)
has always worked for me, and is actively used in several of my published addons.
If you're seeing an error, in order to tell you why, we need to see both your actual code, and the actual error.
