FileMaker Pro 9: The Missing Manual by Geoff Coffey, Susan Prosser This errata page lists the Changes made in the 12/07 printing. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification (373) "you can get into trouble (Figure 8-20)." Should be Figure 8-19. (375) "display data from almost all your tables (see the top TOG in Figure 8-19)." Should be Figure 8-20 [455] First, change the first sentences of the third ¶ on page 455 like so: "This behavior comes in handy when you're fiddling with dates in calculations.

Then we also change this, starting from the fifth ¶ on the same page: -------------------Start Edit-------- To get the last day of this month, just change the day parameter to "0" (it's the middle "1"). Here's a commented version of the final formula: Date ( Month ( Order Date ) + 1 ; // the next month 0 ; // the last day of the month referred to in the parameter above, or ?this? month Year ( Order Date ) // this year ) -----------------End Edit----------- (664) Note; missing a quote mark
