A rollup field aggregates specific cells from records that are linked to another field in your table. For an overview of rollups, check out the Guide to Formula, Lookup, Count, and Rollup Fields.
The following functions can be used to aggregate your rollup values.

| ARRAYUNIQUE | Return only unique items. |
| AVERAGE | Mean average of the values. |
| CONCATENATE | Joins together the text values into a single text value. |

| COUNTA | Count the number of non-empty values. This function counts both numeric and text values. |
| COUNTALL | Count the number of linked records. Choosing any column of the linked table will produce the same result. This function counts all values including blank records. |

| MIN | Returns the smallest of the given values. |
| OR | Returns true if any one of the values is true. |
| SUM | Sum together the values. |
