Sorry Mike, I sending you this new image, I hope you understand me now

Ok Mike, sorry for this again
I´m trying to explain myself as well as I can

We should forget all of the above and start again...

ok, I have my ultragrid in groupbyrows (my table have 3 columns, Zone, Subzone and mts),
like this:

 +zone
    +subzone
        mts  

so, in the beginning, i didn't know how to change the description text for each groupbyrow,
for that, I used InitializeGroupByRow and I changed for a custom text  the description of each groupbyrows
using  e.Row.Description="My custom text"

everything it's ok here (IMAGE 1 AND 2)

But  I need the sum of the column "mts" and put it in the groupbyrows ((IMAGE 3)
In this part is where i'm having problems, because in the groupbyrows the result Of The Sums
is displayed with along the source column (mts): some like this: "mts sum=[resultOfTheSum]"
To change sum=[resultOfTheSum] for a custom text (IMAGE 4) , I used:

summary.DisplayFormat = "Total of meters = {0}"


but, mts is still diplaying with along my custom text "Total of meters = {0}". (IMAGE 4)

What can I do to remove "mts"?
What could be happening?
