use local variables..
using global variables like you are doing is a bad practice, as you'll eventually over-write information you weren't meaning to when you inevitably use the same variable name a second time.
---
For your issue;
You should check that the file exists before using it.
More then likely mounts.txt does not exist in the file directory you are currently using.

function onSay(cid, words, param)
    local file = io.open('mounts.txt', 'r')
    if file ~= nil then
        local notice = file:read(-1)
        doShowTextDialog(cid, 7528, notice)
        file:close()
    else
        print("Unable to find file 'mounts.txt' in the directory you have chosen.")
    end
end

I think you can catch the error, it might be other reasons why a file cant be read. (etc permission issues on linux).

local file, err = io.open("mounts.txt", "r")
if file then
    -- do stuff, then close the file. 
    io.close(file)
else
    print("Error opening file: " .. err)
end
