Hello @Rahi - The error message says this: > ValueError: invalid entry in choice array > Check that the Soil Group raster does not contain values other than (1, 2, 3, 4) Your soil group raster does contain values other than (1,2,3,4), it contains the value 13. The [Data Needs](https://storage.googleapis.com/releases.naturalcapitalproject.org/invest-userguide/latest/en/urban_flood_mitigation.html#data-needs) section of the User Guide specifies values of only (1,2,3,4). [The Data Sources Appendix](https://storage.googleapis.com/releases.naturalcapitalproject.org/invest-userguide/latest/en/urban_flood_mitigation.html#appendix-data-sources-and-guidance-for-parameter-selection) provides information about how to handle this. ~ Stacie ---
