Answer 1

If you look at the documentation of the <display:column> tag, you will find the following description for the total attribute:

total: If true, will total the contents of this column. This value is available via the Map named in varTotals for the table. Column values need to be Numbers.

So please check if the columns FTD, MTD and QTD are numbers.
