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

Func DoFunc()
    Sleep ($Refresh)
EndFunc

And error is long

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
