How to mapping and return target data ?
2 Ansichten (letzte 30 Tage)
I have 2 matrix:
I try to map A.Var2 and B.Var1, if they are same value
they should return B.Var2 into A.Var5 in the same row.
It look like vlookup function in excel,
I try to use this code
but I face a problem with this error "Data inputs must be the same size, or any of them can be a scalar."
How can I fix it ?
thank you in advance
