The solution is to use the Job Info variables available in Watch. To do this, you first have to setup your form. Open your form, and create a new Data Selection object. A window will now open, and you will be able to select "Custom data selection". Check it, and you now have a list of string to display. Click on the first one(you should have only one), and enter "=&Watch.JobInfos[1]". The value of this field will be equal to the Job Info variable #1. If you want to see the result without using Watch, go in the Format->Document menu, and select Job Infos to the left. You can now enter values for Job Infos, and they will appear on the form. Enter a value to job #1 to test the form.
Now, once it's setup, open Watch and your process. Insert an action, and choose Set Job Info. Choose index #1. Next, right click on the "Value" text box, and select "Variables". You now have a choice of variables to choose, such as the current day, month or year. And you can select more than one too, and you can also manually type some characters to the "Value" text box. So if you type the following: "%m\%d\%y", job #1 will contain the current date in a MM/DD/YYYY format.
Once done, run your Watch process, and print out your form. The value you entered in the Job Info will now appear on the form where you placed the Data Selection object.
Hope I solved your problem.
