Personal billing app

Personal billing app

  

Hello everyone. I developed an application for personal billing organization. But now I'm facing a problem ... I need to add selected invoices, where I get the total amount back in one field, then I need to enter the amount paid to finally return the difference value in another field.

André,


To give you a more accurate answer I would need more info.


But you probably can achieve what you need with the OnChange event the input widget and the Ajax Refresh.


Cheers,

Renato
