The error message doesn't prevent the evaluation from taking place. In this case it acts more as a warning. You may eliminate this warning using Quiet: In[1]:= Partition[Range[10],m]/.m>3//QuietOut[2]= {{1,2,3},{4,5,6},{7,8,9}} Alternatively you can write the ReplaceAll inside the brackets: In[3]:= Partition[Range[10],m/.m>3]Out[3]= {{1,2,3},{4,5,6},{7,8,9}} or you can use With: In[5]:= With[{m=3},Partition[Range[10],m]]Out[5]= {{1,2,3},{4,5,6},{7,8,9}} In all cases, m has to be a positive integer; otherwise the error actually prevents the evaluation. The definition of Partition doesn't make this explicit but I guess it goes without saying. Tomas
