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.) ?

Where do I include this?  In the Value window?  Like this?

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

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.
