Top 5 Reasons to know the Let() function
I can certainly understand why the Let function isn’t the first thing newer FileMaker developers decide to learn. First, it’s a very complex looking function, and it isn’t inherently obvious in terms of the benefits you’ll receive for knowing it. And, second, it likely just doesn’t show up on the “must-know” radar until you see it used in an effective way.
However, the second you realize its true value, it becomes a must use function. I actually can’t see how someone would develop in FileMaker Pro without using it. It’s the ultimate code organizer. It makes things clean and provides so many opportunities to keep your overall code base much smaller.
In this video, we take a look at the Let function and my top 5 reasons for why you should know and use it. If you’ve got more reasons, then please add comments on the article page!

I want to know how to set different color format in expression. Just likes your demo video.
My FileMaker only show black.

I found it's MBS plug in for syntax coloring now.

I love the Let function!
One plus for Typinator. I've been using it for about 6 years. I have FM functions, my own functions and lots of other cool TidBITS. When Dropbox came out I moved my library to it, so I can use the same functions on all my computers.
MBS is also a very good tool for syntax coloring and searching within the manage database window and scripts. I also got Christian to highlight which if function opening and closing lines belong together. Check it out!
