math operators don't sum if same value

[Dave]

I have this macro that sums up values from three different fields:

\define vassum2(here mynow)
VAS total: {{{[title[$here$]get[vashi.$mynow$]] [title[$here$]get[vaslo.$mynow$]] [title[$here$]get[disabil.$mynow$]] +[sum[]]}}}
\end

\define vassum()
<$macrocall $name=vassum2 here="$(currentTiddler)$" mynow={{mynow!!my-now}} />
\end

<<vassum>>

It works great as long as each of the three numbers is unique, but if for example the values are 8,3 and 3, then the total is presented as 11, not 14

Is there a work-around for this?

Thanks,

- Dave

Yes, there is.  see https://tiddlywiki.com/#Dominant%20Append

By default, items in a list are "dominantly appended", which automatically "de-duplicate" the results, so that individual items will appear only once in the resulting list

Of course, as you have discovered, this is not appropriate when using math operators.  To work around this, you can use the "=" prefix in front of each filter run, like this:

{{{ =[title[$here$]get[vashi.$mynow$]] =[title[$here$]get[vaslo.$mynow$]] =[title[$here$]get[disabil.$mynow$]] +[sum[]] }}}

enjoy,

Thanks again Eric - that fixed it :)
