Calculation Merge Tags – List Field Calculations

Docs » List Number Format » Calculation Merge Tags – List Field Calculations

The GravityWP List Number Format add-on extends the standard Gravity Forms List field by enabling number formatting and built-in calculations. This documentation outlines how merge tags can be used for list field calculations, such as column totals and row-level operations inside List fields.

Functionality Overview

When number formatting is enabled on a List field column, you can:

• Reference specific columns in calculations
• Perform row-level calculations inside the List field
• Calculate column totals using a Number field outside the List
• Count the number of rows in a List field

Merge tags are context-aware. The same tag may return a row value or a column sum depending on where it’s used.

Column Totals and Row Count in List Field Calculations

You can use merge tags in a Number field outside the List to display the sum of a specific column or count the number of rows in the list.

Column Total (Sum)

{List:1.2}

• Returns the sum of all values in column 2 of List field ID 1.

Row Count

{List:1}

• Returns the number of rows currently filled in List field ID 1.

These are commonly used for subtotals or summary fields.

Row-Level Calculations Inside the List

You can configure a column in a List field to calculate its value using other columns in the same row.

Example:

{Order Items:1:2} * {Order Items:1:3}

If column 1 is Quantity and column 2 is Unit Price, this formula used in column 3 will calculate the total per row. When used inside the List field, merge tags like {List:1.2} refer to the value of that column in the current row.

Merge Tag Syntax for List Field Calculations

Labels Are Optional

Gravity Forms and GravityWP merge tags only require a valid field ID — the label part is ignored. This means the following examples are all valid:

{:1} — Refers to field ID 1
{:1.1} — Refers to column 1 of List field ID 1
{notthelabel:1} — Still works, because only the field ID matters

Use any label or even omit it entirely — as long as the field ID is correct, the merge tag will function.

Notes

• Merge tags work in any Number field or calculated List column.
• The same merge tag can return different values depending on where it’s used.
• If merge tags do not appear in the dropdown, you can manually type them.
