[Solved by incapaxian] Converting a "Key" of a Dictionary to String?

Since I'm tired, it's 4:40 AM and I can't seem to figure out a solution...

I bothered myself to beg the question, "How could I get a string from a key in a dictionary"

Here is my current code:

local functions = {}
        local function searchTable(tab,nam)
            local parent = ""
            for i,v in pairs(tab) do
                if CVExtra[tab] then
                    parent=""..nam
                else
                    parent=""
                end
                if typeof(v)=="function" then
                    table.insert(functions,""..i)
                elseif typeof(v)=="table" then
                    searchTable(v,i)
                end
            end
        end

table.insert(functions,""..i)

Trying to convert "i" to a string, which might equal "numbify" but "numbify" is a function, defined within the dictionary of "CVExtra."

print(i) is able to print out the name, but I don't know how to do the same.

I wonder if any one can provide the print() function code if no true solution can be made.
