How can I create an alternative to 28 levels of nested IF's?

Hi All,

recently my model has started to give me Circular Errors that I have not had before. (Maybe because I did and Office 365 update). I read somewhere that if there are too many IF's that this could cause the problem. And indeed elsewhere in the model, I changed a multi level IF statement and that circular error was fixed. So I guess there is a truth to the statement.

However, in this case, I am not sure what to do. I have an equation which is 28 levels deep with a nested IF. All of the examples and videos I have seen using alternatives to Nested If's are very simplistic and don't really give me any help. The aim of this formula is to identify patterns in the numbers, such that:

If:
A4 = B4, B4 = C4, C4 = D4, the pattern is "same same same"

Or If
A4 < B4, B4 > C4, C4 < D4, the pattern is "up down up" and so on.

Currently, the nested IF's pulls out 26 different patterns.

I am not sure how to construct an IFS, CHOOSE or VLOOKUP equation that can replace this nested IF rats nest to fix the circular reference.

Can somebody please give me a big push into the direction I should be heading.

Thanks

The circular reference tracker is, in my experience, quite infuriating. I often just clear entire columns one by one until it stops reporting a CR, then reinstate the last one deleted and check again. If the CR reappears, at least I know it should be in the column just reinstated.

Office 365 customers have access to Waterfall charts since late 2016. They were added to Excel 2019.

Ok, looks like my primary file has corrupted. I have opened a copy from two days ago and there aren't any c.r.s

I'll work from that file.

thanks for your help.

Not sure exactly what you came up with but what about this as a replacement for that very long formula?

Good Morning Peter_SSs,

I appologise that I didn't look at this last night. I guess I got so carried with with multitude of c.r's that appeared from no where that I had to put everything aside for a while.

I am just in awe of the knowledge in this forum. This formula is fantastic at is the preferred solution that will be implemented today.

Thank you kindly.
