Purpose
Function to returns the total value of a column for a matching series of keys
Syntax

Description
The SUMVALUES() function returns the total value of <expN> for a matching series of keys. The required <expN> parameter should be a numeric expression referencing columna from the current workarea (or cursor). If none of the optional parameters is specified, then the keys matching the current key is scanned. An optional <for condition> can be specified to restrict the rows included in the sum operation. You can also optionally specify a <key expression> to perform the sum on instead of the current key. An optional <tag name or index order> can be specified also.
After completion, all record pointers and indexes are returned to their original positions.
Example
use customer order title // Sum the balance column for the number of records matching the current key total_balance = sumvalues(balance) // Sum the balance column for the number of records matching the key "Mr" m_male = sumvalues(balance, .T., "Mr") //Sum the balance column for the number of records matching the current key with an expiry date < today m_expired = sumvalues(balance, expiry < date())
