Getting the following error in Enterprise Miner

PruthviBhupathiraju — Thu, 24 Jul 2014 19:20:15 GMT

I am getting the following error when trying to run the decision tree node in enterprise Miner:

ERROR: A character operand was found in the %EVAL function or %IF condition where a numeric operand is required. The condition was: n+1

ERROR: The macro EM_TREE_RUNTREEPROCEDURE will stop executing.

Can you please let me know the reason?

%eval wants either an integer literal or a macro variable that resolves to an integer.

%let n= 5;

%let x = %eval(&n +1);

%put &x;

You can get this message in %if or %do loops as well as they have implicit calls to %eval that you don't see. The place you have n+1 needs &n+1.

How do I correct this error in enterprise Miner.

Without seeing the code generated other than the suggestion about &n+1 instead of n+1, no idea.
