Linking of R3/ button with a button put using HTML code

Hai,

I have put a button in my service file using the below command,

<input type="button" name="Exit" value="Go to Google" >.

In my Dialogue program i have a "BACK" button. When i run the service file i want to hide the "BACK" button of the dialoge button and i want to link the function code of BACK button to "EXIT" button of service file.

In other words i want to link the function code of A dialogue program button to the button which i have put in the service file using HTML code.

Thanks & Regards,

H.K.Hayath Basha.
