I have posted this previously but unfortunately my account got scrambled and I have had to start again. I need to do a domain analysis of some data.   Outdoor Team Non-team Leisure Domestic     15          5           0             0            25      60         0           25           10           0      0           25         30            0            0   I need to show the proportions each of these contribute to the whole so results should look like this Outdoor  10% Team       25% Non Team  45% Leisure     15% Domestic   5%   I have on previous suggestion tried proc iml   proc iml; use domains; read all var _num_ into x[c=vname]; close;   ratio=t(x[+,]/sum[,ncol(x)]); print (t(vname)) ratio[f=percent8.2]; quit;   but I got this message in the log   114 115 proc iml; NOTE: IML Ready 116 use domains; 117 read all var _num_ into x[c=vname]; 118 close; NOTE: Closing WORK.DOMAINS 119 120 ratio=t(x[+,]/sum[,ncol(x)]); ERROR: (execution) Matrix has not been set to a value. operation : [ at line 120 column 18 operands : sum, , _TEM1002 sum 0 row 0 col (type ?, size 0) 　 _TEM1002 1 row 1 col (numeric) 10 statement : ASSIGN at line 120 column 1 121 122 print (t(vname)) ratio[f=percent8.2]; ERROR: Matrix ratio has not been set to a value. statement : PRINT at line 122 column 1 123 quit; NOTE: Exiting IML.   I really don't understand this procedure at all so have no idea how to fix it.   Can anyone help?   Thanks. ...
