InfoPath Dev

Maybe somebody can help me out with the following. I am a newbie and know almost nothing of InfoPath 2003. I was starting with it because I need a form to make a part of my work easier. My question is the following. I am building a Video conference request form. I have made 2 text boxes, one called Time CET and the other Dial in time. For both in the textbox properties I have made the Data type time.

What I want is the following. The user fills out Time CET and automatically the dial in time appears but 15 minutes before the dial in time. For example Time CET is 14.20 hours then the dial in time will be automatically 14.05. Sorry if my English isn#%92t correct but I am from the Netherlands

Hi Evert and welcome to the forums!

On the OnAfterChange event of the field that the user inputs to, try this code:

DateTime f1 = DateTime.Parse(e.Source.text);
DateTime f2 = f1.AddMinutes(-15);

thisXDocument.DOM.selectSingleNode("/my:myFields/my:field2").text = f2.ToShortTimeString();

Hi Matt,
