Hello monkeysaurus and team,
Thank you for your kind reply and the onchange suggestion. Some success was observed but need a little more assistance
Given:
1. I currently have within the tags for Field "A" I have onclick="ds_sh3(this) which is an original Calendar function. (calendar works)
2. I have added onchange="upDate('date3', 'date4') to add 7 days and returns result to field "B". (onhange doesnot trigger)
Note: Field "A" Calendar works however onchange was not triggered Field "B" remained blank.
Next Steps:
3. Removed onclick="ds_sh3(this) which is the calendar function
4. Manually changed date in field "A" onchange triggers Field "B" displays new date +7 days (cool)
Conclusion
onchange does become active if the change in a field is generated via function
Question
Sorry to say that I am not familiar with jQuery UI but can I still use JavaSript fuction to select a date for Field "A" and have the fuction that adds 7 days automatically triggered by either using onchange, another type of tag controller, or automatically force a change? if so how? if not why? and most importantly thanks!!
