# ERR\_RECIPE\_SPLIT\_INVALID\_COMPUTED\_COLUMNS: Invalid computed column[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_RECIPE_SPLIT_INVALID_COMPUTED_COLUMNS.html#err-recipe-split-invalid-computed-columns-invalid-computed-column "Permalink to this headline")

There is a computed column on that Split recipe that has a name conflict. The split recipe need unique names for all input and computed columns, case-insiensitive.

The name conflict can happen:

* between computed columns

* between a computed column and an input column

* between input columns (on a case-sensitive dataset, there might be

2 columns where case is the only difference)

## Remediation[¶](https://doc.dataiku.com/dss/latest/troubleshooting/errors/ERR_RECIPE_SPLIT_INVALID_COMPUTED_COLUMNS.html#remediation "Permalink to this headline")

Check the names of the computed columns and input columns, keeping in mind the case-insensitivity.
