But that's more problems than can be answered within a single answer or question. You've specified format definitions but not applied them and your data doesn't appear to align with your format definitions. You also have the issue where you're data doesn't appear to match your format specified so I'm not sure what to say about that. So the final code should look like: CLASS c1kdscc3 (REF= " Often or more (Ref)") / PARAM = ref Ĭode to replicate the issue if desired, note I had to do this because we can't run your code without: proc format To match your format: 0 = " Often or more (Ref)" I can replicate the problem and error with the code below.įix it by changing: CLASS c1kdscc3 (REF= "Often or more (Ref)") / PARAM = ref It's the mismatch between your formatted value in PROC FORMAT and the value you specify in the CLASS statement that causes the issue.
