Specify a date range for a date field.

Question

Hi folks,
I have cobbled together some javascript using code that someone provided in response to my thread about setting a maximum length between two dates as reference.
My aim is to enforce a minimum date of 01/01/2014 and a maximum date of 31/12/2014. Any date entered that are outside of tis range should result in a warning message.
When I use the below code, I find that the warning message pops up before I ahve even had a chnace to enter any dates, and also when I enter an invalid date it pops up over and over until the program crashes.
Can anyone tell me how I can fix this?
Cheers.
function Scand(cFormat, cString) {
var oDate = util.scand(cFormat, cString);
if(oDate == null) app.alert("Error converting date " + cString + " with format of " + cFormat, 0, 0);
return oDate;
function GetField(cName) {
var oField = this.getField(cName);
if(oField == null) app.alert("Proposed Completion date cannot be more than 180 days after Commencement Date. Please revise " + cName);
return oField;
var date1 = (GetField('Field 30')).value;
var cDateFormat = 'dd-mm-yyyy'; // adjust to match input field's format;
var oDate1 = Scand(cDateFormat, date1)
var nDate1 = Math.floor(oDate1.getTime() / (1000 * 60 * 60 * 24))
if(nDate1 < 01-01-2014) app.alert('Date cannot be earlier than 01/01/2014');
if(nDate1 > 31-12-2014) app.alert('Date cannot be later than than 31/12/2014');
this.getField("Proposed Completion Date").setFocus();
event.rc = false;

When putting in Epoch time, do I just literally replace the dates in if(nDate1 < 01-01-2014) with the Epoch time value e.g. if(nDate1 < 1388531238)   because now its not calculating correctly, or am I misunderstanding what it is?  I tested by putting in today's date 19/02/2014 and still got the alert saying that it was before 1/01/2014...
