I am having an issue with a form that has Javascript enabled.  I had to write a script to build a table that acts as a weekly time sheet with default times for M-F with Sat and Sun defaulting to no times.  This also includes sections for each day of the week for Overtime, Vacation, Holiday, and PTO hours.  The final column in each row adds up the daily total.  This is part is working.  (The additional hours fields currently do not calculate based on hours and minutes, just hours.  I will be addressing that part in the future.)

The trouble is any fields outside of this primary table.  I am trying to calculate weekly totals for each field but unable to get this to work properly.  The built in SUM() function will not total these rows nor can I seem to write out to a field outside of the table.  (Such as the Single Line Over Time Total field that I designated as .totalOT in CSS.)  I am fairly sure that the built-in functions will not work since I am dealing with times and other data types that are not numbers, is that correct?  If so, I will need to do the calculations within Javascript and until I can figure out why I cannot write outside of the able, I am quite stuck.  Any help would be appreciated since I am new to Javascript.
