Is the checkbox field a multi-select checkbox?

I have some clarifying questions to help you resolve:   Can the user see the Documents tab on the left-hand side of the project screen? Can the user see other documents or proofs in the project but not this one? What is the License Type of the user in Workfront? (Planner, Worker, Standard, Light, Co...

Can you explain a little more about the connection of the objects?   Was the issue converted to this project and, therefore, tied together as resolvable objects? Or are the issues inside the project?

I have a couple of follow-up questions:   What type of field is the project manager assignment? Is this a project report and the field lives at the project level on the custom form?     One thing you can try doing is forcing the sort. If you switch to text mode on that field and add this: sortOrder=...

You should be able to add "convertedOpTask" to the front to reference the resolvable issue/request fields.

Took some trial and error over the years. Even if you are new, you'll get there. It calls out the order on the documentation page but doesn't explain how you can use it for something like this very well. It's kind of similar to Excel conditional formatting.     Rules are applied in the order that th...

So you can trick the system with conditional formatting by setting up 2 conditional statements. Workfront will go down the list and apply the first format and then the second format.   Set your first condition to color the completed projects white, then set your second condition to color the at risk...

It is not an option natively within the tool, but you could report it with conditional formatting. This could also be done through Fusion if you have it. 

The text mode code you are using is specific to pulling in a collection of data on a project report (listmethod=nested(tasks).lists) which isn't necessary and won't work here since it's specific to a project report collection.   You can natively pull in a task milestone ID to a note report, so you d...
