How to compare Date in the TextField or DateTime with Date/Time field?

Question

Hi All,
I am facing an issue with respect Date comparinson. I tried to look into entire discussions but failed to get the answer.
My issue is: I wanted to comparet Date/time field value with Date value which is in TextField.
The functionality of my form is:
I have dropdown list which lists the registered customer ids binded to XML Datasource. On selection of the customer id from the dropdown I am displaying customer registration date in the TextField or say Date/Time field as below code in dropdown change event.
RegistrationDetails.PurchaseEntry.txtRegDate.rawValue = regDataNode.CREATION_DATE.value; (this is TextField control)
In form I have an Date/Time field in which use will select the date of item purchase. In the validation part I want to make sure that, the purchase date selected in Date/Time field must be greater than the Customer Registraiton Date. I able to compare if the customer selects the date from two different Date/Time fields. But how to compare the dates which one is in Date/Time field and Date is in TextField?
I have tried using Num2Date and Date2Num with "YYYY-MM-DD"  format to compare but not succeed!
Can you guys help me in this? Thanks in advance
Regards.

Hi,
Yes, I am able to display the date which I have assigned to the text box. In the message box it show the value as '31/05/2009', since in this format i am assigining the date in the text box.
Here is the code which I am assigning the value:
RegistrationDetails.PurchaseEntry.txtRegDate.rawValue = regDataNode.CREATION_DATE.value;
Do I need to change the format while assigning value in text box?
You have told that, you have attached your test form, nothing is the reply. Can you repost the file?
