The issue happens because you selected the internal key property pzInsKey instead of the actual business field. In the Configure Condition step, you should not use system-generated keys for comparison. Instead, select the correct property that holds the founding total value from your data model, such as .FoundingTotal. Make sure the property is defined in the class and is available on the clipboard page. Replace the condition field so it points to this business property rather than pzInsKey. This will ensure the rule evaluates correctly and the error will be resolved.
