Using a check box

I'm using a check box to keep track of issues in a large database.  I want to verify the status of the check box and it's working well if the check box is checked (Yes) or unchecked (No), but how do I know if the check box is "undecided"?

If a checkbox is undecided, @IsBlank will be True.

If @IsBlank(MyCheckbox)
{
       ... Do stuff
}

No, that won't work. SBasic will force the value to either 1 or 0, since it knows it's meant to be treated as a Boolean value.  Booleans do not have three states at code level.
