I have to recreate the 'repeat event' functionality you would find in a calendar app such as Apple's 'calendar' etc.

 

I have been looking around from a modular solution but haven't found anything. Before I begin does anyone have a suggestion, 

Do a google search for Calendar and FileMaker, and check out SeedCode’s Free Calendar.

 

p.s.

It’s a lot of fun and can be a real challenge to create one from scratch. 

challenge yes, fun not so much.

 

Almost done though. I am trying to

a. find the difference between each number in an array:

b. then find the difference to loop back to the first number + 7: 

 

2  — Mon

3  — Tue

6  — Fri

 

needed result:

1   [tue - mon]

3   [fri - tue]

3   [next mon - fri]

 

 

 

I am not sure I would go that way, but in any case =

Mod ( y - x ; 7 )

will return the results you are looking for.

I am a zero for the custom frequency. So I am open to suggestions.

My plan was to determine the sequence of days selected in weekly and the calc against start date, then multiplying by the loop 

This is not easy (and I am not eager to get into it). I suggest you asses your exact needs on this - because the more generic you will try to make this, the more difficult it will be. Case in point: this "sequence of intervals" that you wanted to compute depends upon the day of the week where the first occurrence of the event occurs; it can be "1, 3, 3", "3, 3, 1" or "3, 1, 3".

That makes sense. All repeats above custom are all calculated from the initial date not sure why I lost sight of that.  Thanks

I like your Recurring Event layout! Nice balance!

thanks LaRetta.  I will condense will popovers etc. once solved

I agree - you're layout looks really stylish; well done.
