Changing Field Style for Problem Tasks if due date is passed

[Joe Taylor]

I'm trying to change the font color of the due dates in the list view of PTASKS if the due date is past, but no matter what I try it doesn't seem to work.

Here's what I have now:

Table: Problem Task [problem_task]

Field Name: Due date

Value: javascript:gs.dateDiff(current.due_date.getDisplayValue(),gs.nowDateTime(),true) <  0 ;

Style:  color:red;

What am I doing wrong?

Also, where can if find a comprehensive list of styles  (colors, background, font sizes, etc.) ?

Hi MB.  Any guidance for my last question?

Open the same style sheet which you created for problem_task table >> change the table to Task [task] >> insert and stay. With this you will have a copy of this style for task table.

In case you only want it to be only for problem_task record (but visible on task and problem_task) then ignore my previous comment and update the existing style which you have on problem_task table to look like this-

Table: Task [task]
Field name: Due date
Value:

javascript: var answer = (current.due_date.getDisplayValue() <= (new GlideDateTime().getDisplayValueInternal())) && current.sys_class_name == 'problem_task'; answer;

Style: background-color: red

Sorry about that.  Don't know how I missed that update.  Tanaji's answer below should do the trick for you.

Sweet!  That last value script seems to do the trick.  I'm seeing the red dot on all due dates in the past.  

Hate to press my luck, but what if I don't want this style for tasks that are "Closed Complete"?
