To use recordtype within an editable grid

Hi everyone!

I´m doing an interface using Recordtypes from scrach. I´m making a grid in a form to sum some quantities from de employers. I´m having some problems with the dynamic link to add new rows of employeers expenses and also having problems to summarize the fields with the quantities. I´m providing part of the code. Could you tell me what i´m doing wrong please? Thanks a million in advance!
