Solved: input box filter

[justdream]

Dears,

I'm using input box filter to allow users entering their required data to be selected and filtered
as shown

Area = InputBox("Enter your required Area")
Range("A1").AutoFilter Field:=1, Criteria1:=Area

but I faced special case: some users want to select two variable (example: filter for Asia and USA)

how could I let users select multiple inputs
using above input box filter??
