Mandatory Field not Mandatory!

[Cirrus]

All,

This should be easy, shouldn't it? Using UI Policies, when a call comes into ServiceDesk, they can select a call type. For one particular call type (X), they then select a sub-type which is a mandatory selection. If that sub-type selection is 'Y' then a new true/false field called Terms and Conditions (u_tc) will appear. We want u_tc field to be mandatory also, but when I create a new policy which is applied when Type = X and Sub-Type = Y, with the UI action set as u_tc mandatory = true, visible = true, the user can still complete the ticket without checking u_tc. 

I have even tried an On Load client script (removing the mandatory = true portion above so that the field still appears):

function onLoad() {
//Type appropriate comment here, and begin script below
if(g_form.getValue('y') == value)
g_form.setMandatory('u_tc', true);
}

What am I doing wrong here?

Thanks GGG. This is how I have it currently and still the field is not mandatory. I am sure its to do with it being a true/false field

You can't make True/False field mandatory using UI policy

You have to either write an onSubmit client script or change to field choice type with Yes/No values

correct. if the field is false it HAS a value: FALSE.

you CANT make a true false field mandatory.

change it to a drop down with Yes / No as the selections.

Thanks everyone, I have written an on submit client script that alerts the user if the yes/no field is not checked
