When I click and drag down the next cells in the proper image, in cell "E21" appears a '3' resulting from tracking the cell sequence from "A15" to "A18" as I do to just loop in cells from "A15" to "A17"? for the result to exit "Waiting" ??
ByattachingthecorrespondingcellsA15toA17andaddingan"if" function on A18 through C18, saying that if it is different from 1 to 3 and setting these values, call the "incorrect" cell if you add some number outside the sequence of 1,2,3.
