Creating a Formula from the Properties side panel

You can set a formula on a form item using the Properties side panel. The following instructions describe how to open the Formula editor and the formula options available.

About this task

You must set the formula on the form item that stores the result. For example, if you want to add two numbers together, set the formula on the field where you want the result shown.
Note: If you are creating a formula to assign a string value to a Time form item, the content of the string must be based on a 24-hour clock. If the input value is not in a valid 24-hour clock format, the resulting value will not be correct.

Procedure

  1. Select the form item.
    The Properties side panel opens.
  2. Click the Formula tab.
  3. Select the function from the list of available options.
    The available options are:
    • Add – Adds two values together.

    • Concatenate – Concatenates two values together into a single string.
    • Power – Raises power of one value to another value.
    • Table Max – The maximum column value of a table on the form.
    • Multiply – Multiplies two values together.
    • Minus – Subtracts one value from another value.
    • Table Sum – The sum of a column of a table.
    • Table Count – The number of rows in a table.
