Ok, no offense mate, but don't edit a different code into it when people are trying to help you figure out the original. I was confused there for a sec...

Try separating the function out to test functionality better:

local f = CreateFrame("Blah")
f:SetScript("OnUpdate", testfunction(self))

function testfunction(frame)
    if not foo then 
        local foo = "foo"
        local bar = "bar"
    end
    text=foo..bar
    DEFAULT_CHAT_FRAME:AddMessage(text)  -- test to make sure everything goes smoothly
end

Also note that I removed local text = "" as you don't need it. It's already going to be overridden each time without having to manually clear it. After you get it working how you want, then go back and optimize the code (as haste pointed out).
