Hello @marcn ,

Yes 

try below  script

var mvrsvalues= JSON.parse('mvrs_name');
g_form.addInfoMessage(JSON.stringify(mvrsvalues)); // to print the JSON


//Below code is to access the JSON elements
 for(var i=0; i<mvrsvalues.length;i++)

{

g_form.addInfoMessage(mvrsvalues[i].your_variable_name_in_mvrs);

}

Please mark my answer correct if it helps you

@marcn  thanks for marking my answer helpful and please mark my answer correct if it helped you so that it will be removed from unsolved list.

And for you question to compare two values you can use below script

But change you script to on submit in on change you cant do it

function onSubmit() {
    var value = g_form.getValue("your mvrs name"); 
    var mvrsArr = JSON.parse(value);

    var comparedValue = compareValues(g_form.getValue("your column variable back end name to check "), mvrsArr)) 
 alert(comparedValue);
   
    
}

function compareValues(valueToBeChecked, mutiRowArray) {
    for (var i = 0; i < mutiRowArray.length; i++) {
        if (mutiRowArray[i].your_variable_back_end_name == valueToBeChecked) { 
            return 'valueFound';
        }
    }
}

Hi,

you can access complete JSON of MRVS only in onChange or onSubmit catalog client script which applies to either Catalog item or a variable set(not MRVS)

You cannot access complete JSON if you are writing onChange script on 1 of the variable within MRVS
