When a summary field is also used as the break field, returns the summary field value for the entire found set of records (a grand summary value).

Use GetSummary to capture summary values when you want to:

  • use summary values in a calculation
  • display subsummary values in Browse mode or in a body part

Calculations using the GetSummary function are unstored.

Notes 

Example 1 

GetSummary(Total Sales;Country) returns a summary of all records pertaining to the value in the Country field.

Example 2 

GetSummary(Total Sales;Total Sales) produces a summary of all records (similar to using a summary field, which is a total of total sales).

Example 3 

If(ThisCharge > 3 * GetSummary(AvgCharge;Customer), "Verify this charge", " ") displays Verify this charge if the current charge is greater than three times the average charge.

Example 4 

GetSummary(Total Sales, if(Number of Countries > 1, Country, Sales Zone)) returns a summary of Total Sales by Country if Number of Countries is greater than 1. Otherwise, it returns a summary of Total Sales by Sales Zone.
