Error message , what does it indicate?

[Koichi_Tsuji]

First time to see error like this. What is the possible problem behind to debug the issue?

Expression appears to be part of a cycle: [Voyage Number] :: 22MORE INFO

[Aleksi]

It sounds that you have created an endless loop with two or more columns/formulas.

[Koichi_Tsuji]

What is the typical reason for the infinite loop to happen when it comes to appsheet/list expression?

I keep trying to find the root cause, but failing.

[Aleksi]

For example if two columns have an app formula and they are both reading other’s value.

[Koichi_Tsuji]

In case we need to use tow VC in expression is there any way to stop looping?

[Steve]

You might be able to avoid the cycle by using actions to update normal columns, rather than using virtual columns.

Can you provide more details about the columns and expressions involved?

[Koichi_Tsuji]

Hi Steve, thank you for hints.
I change VC onto physical column as much as possible and to avoid one column to refer to another one, and vice versa.
And then i used API, by triggering workflow due to change value in VC column.

What do you mean by “tow”?
