Invalid Parameter message when using kernel density

[HayleyMaynard]

Hi,

When I try to use kernel density analysis on my imported (from Excel) data, it says that it failed to execute kernel density due to Error 000875 Output Raster and Error 000581 Invalid Parameter.  How do I fix this?

Thanks in advance,

Hayley

did you rule out the error messages?
