Clear Radio Buttons based on a People Picker

[Lana]

Hi,
I want to clear the Radio Button Selection if a People Picker is Blank.
How would I do this? Right now, we select a person, then we use the Radio Button to indicate their level, Expert, Advanced, Competent or Novice.
When we remove the person’s name, I want the Radio button to clear….since you can’t use a People Picker in a rule, I am unsure of how I can do this….
Thanks!

Hi,
People pickers can be used as triggers in SP2013, but if you are on SP2010 you can set up this function in the Custom JS:

/* Change "Level" to match you radio choice field name and "PeoplePicker" to match your people picker field name */

setInterval(function(){ 
	var level = getFieldValue("Level"), ppArr;
	if(level !== ""){
		ppArr = getFieldValue("PeoplePicker");
		if(ppArr.length === 0){
			// Clear radio choice
			setFieldValue("Level","");						
		}
	}
},1000);

Hope this helps,
Alexander
