formula works at values but i want it works even after blank cells. it should avoid blanks cell its only consider cell values
please find the attachment

=if(sumproduct(--(a2:d2=a2))=COUNTA(A2:D2),"same","not same")

[martindwilson]

=IF(SMALL(A2:D2,1+COUNTIF(A2:D2,0))*COUNTA(A2:D2)=SUM(A2:D2),"same","not the same")
probably just shortened to

=IF(SMALL(A2:D2,1)*COUNTA(A2:D2)=SUM(A2:D2),"same","not the same")
and maybe if all may be blank to get rid of errors
=IF(ISERROR(SMALL(A2:D2,1)),"",IF(SMALL(A2:D2,1)*COUNTA(A2:D2)=SUM(A2:D2),"same","not the same"))

{=if(sumproduct(if(a2:d2<>"",1/countif(a2:d2,a2:d2)))>1,"not same","same")}
