problem with setcoltypes


I’m just discovering dhtmlxgrid (free version).
I want to make a grid with 5 columns.
3rd and 5th are money, I want to format like “9,999.99€”, so I use
and I get this error :

If I use :
it’s OK but I can’t use mygrid.SetNumberFormat().

I put as attachment my piece of code (the 2 files in the same screenshot) :

and the result of the json :

I would appreciate an help.
Best regards

I answer myself.
The features I want to use : ‘ron’ or ‘edn’ in setcoltypes are not available in the free version.
My piece of code works well with the trial pro version.

I’ll look for an another javascript grid.
