Session Code: COR009


FileMaker Pro has a very powerful calculation engine built into it. The calculation engine is exposed to us in a number of ways: calculation fields, script steps, conditional formatting, filtered portals, web viewers, chart objects, etc. But it can be a challenge to determine precisely when various kinds of calculations will refresh, and what causes them to refresh. This fast-paced session is a survey of the various places where the calculation engine is exposed to us, and an exploration of what exactly causes calculations to refresh their values, and when. Audience participation will be encouraged.


What you should know

Intimately familiar with FileMaker’s calculation engine, and should be moderately familiar with scripting.
