Declare it in a global scope.

Ex; Global $myvariable

$Refresh is local. Make it global.

If you need to have a variable which can be used in different functions then either declare it as Global or pass the variable as a parameter to the function which needs to use it.

Global

Func ReadINI()
    Global $Refresh = 2000;Preferably have Global $Refresh in your main script
    DoFunc()
EndFunc 

Func DoFunc()
    Sleep ($Refresh)
EndFunc

Passing a parameter

Func ReadINI()
    $Refresh = 2000
    DoFunc($Refresh)
EndFunc 

Func DoFunc($iTime)
    Sleep ($iTime)
EndFunc

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
