Hi,

 

It wont be possible to solve this issue using a trigger. What I would suggest is to place a button on your VF Page (on Program Tracker object) which will say "Schedule a Class". Once user clicks on the button; get the data from your text area (may be you can plan to split the strings using a comma or some other special character) and display it in a picklist (apex:SelectList and apex:SelectOption on your VF Page). once user selects it; push it to other text box.

 

While saving the records make sure that you remove the selected value from your text area (you will have selected value in your "selectList" string variable) then you can remove that part from your original field and save that field.

 

Hope this gives you some idea about how to achieve this!!

 

I tried my level best :)

use the string.replace method to replace value that was selected that is found in the text area with ''.

 

String s = 'This is the year time';

String selectedVal = 'year';

s = s.replace(selectedVal,'');

 

result s = This is the time
