mvrs : Need to count number of rows

[Patrick Boutet]

I have a catalog item with a multiple row variable set. 

I would like to display (in another field of the form), information related to mvrs data
For example, number of rows.

I tried with onSubmit catalog script on mvrs but found that this kind of script can't access variables outside mvrs.

Do you have any idea ?

//get the MRVS
    var multiRowVariableSet = JSON.parse(g_form.getValue('variable_set_1'));

var numberOfRows = multiRowVariableSet.length;
