rngTarget =
Range("B3:C11,E3:F11,H3:I11,K3:L11,N3:O11,Q3:R11,T 3:U11,B12:C20,E12:F20,H12:I20,K12:L20,N12:O20,Q12: R20,T12:U20,B21:C29,E21:F29,H21:I29,K21:L29,N21:O2 9,Q21:R29,T21:U29,B32:C40,E32:F40,H32:I40,K32:L40, N32:O40,Q32:R40,T32:U40,B41:C49,E41:F49,H41:I49,K4 1:L49,N41:O49,Q41:R49,T41:U49,B50:C58,E50:F58,H50: I58,K50:L58,N50:O58,Q50:R58,T50:U58")
