Hi,

Can you please post another question?

It is little bit confusing with existing use case.

Please share details like what variable you have on Main form and what should be the price value?

g_form.setValue('price',mrvsData);

var mrvsData = JSON.parse(mrvsStr).length + 1;
//var obj = JSON.parse(mrvsStr);
