Hi Rahul

You could just do this with Jquery as events that run when any of the 3 
fields are exited however I am not convinced that's really a great approach 
- I haven't seen an example of doing this as part of the actual SQLFORM.  
Another question would be do you really need to concatenate them as part of 
your data entry?   If you need them later you could use a 
computed/calculated field or some function to concatenate them when 
required?

Regards
Donald
