may I know how to check page group in a when rule?

hope to check each page in the page group to determine the output.

I can do same on page list by a few functions, like:

- page list contain a page where…

- page list does not contain a page where…

etc.

but seems they do not work on page group.

I do not want to list each page of the page group by specify their index one by one.

@MaxonL16591286Unfortunately, **When rules** do not provide a direct function to check all entries of a **Page Group** like they do for a **Page List** ​​​​​​. Where are you trying to use this when rule? You could perhaps use a **Data Transform** before the when rule initiates to iterate over each entry in the **Page Group** and then use that property in the when rule.

```auto
For Each Page in <PageGroup> 
   If (<Condition>)
      Set .FlagForCondition = true
      Exit Iteration

```

Then, in the **When** rule, simply check if .FlagForCondition = true

@bretw thanks.

I will use the when rule in field visibility so there’s no where to run a DT first.

So I have to list each page of the page group by specify their index one by one in the when rule.

Thanks.
