FileMaker Fundamentals: The Let Function

For some developers, the Let function can be a confusing tool. However, without it, FileMaker calculations would be the eternal mess they used to once be.

The Let function is pretty much a critical tool (in my opinion) that all FileMaker developers should know and use. If only for the reason that it provides the ability to self-document code by using human readable variables.

This video provides a great walk through of how to get started with the Let function and more importantly, explains why you should be using it if you're not!

I see that you have something that allows for color formatting for FM code in textmate? Any chance you would be willing to share that?

Matt, I love your videos...but you lost me at "scope." I'm really trying to learn this, but the video got in waaaay to deep, waaaay too soon. Could we have something more...fundamental?

Hi Matt, I already know and love Let - but even so, I just learned that you can use 'True' and 'False' in calculations. Gems everywhere. Thanks.
