Survival Analysis - Grouping

[HA_md]

Hi,

I am receiving error messages when running the Survival Analysis module. I have chosen Kaplan-Meier Estimate and have selected "Choose field to group by...". I then have select my grouping variable from the drop down menu. When I run the workflow I receive this error:

"Tool #263: Took #6: No valid fields were selected."

The workflow runs when I do not select a grouping variable. I am wondering how I can get the workflow to run with a group variable? I have tried different types of variables such as string or numbers and it doesn't seem to matter. All error out.

Any help would be appreciated. Thanks!

Hi,

Would it be possible to share the packed workflow so we can take a look?

I wouldh have suggested a possible data type issue but as you have said you have tested for that.

I have attached an example workflow that I think highlights the problem. Thanks.

Hi @HA_md, please try moving your "group by" field to the beginning of your dataset:

Please let us know, thanks!
