Numeric Grid question where the one entered value can not exceed another


I'm trying to add in a bit of script to the Sawtooth Price VW sensitivity meter question (which I am using in conjunction with choice) and I want to restrict the question so people have to answer in ascending order. It's a grid question with numeric entry and I want Q1_1 to be the first entered value and Q1_2 the next entered  value. I don't want respondents to be able to enter a Q1_2 value that is lower than the Q1_1 value. and so on for Q1_3 not being able to be lower than Q1_2 etc.

Is there a piece of script that can cause this to bring up an error?

Try setting the custom JavaScript verification to this:

var rows = $('input[name="hid_row_list_[% QuestionName() %]"]').val().split(',').map(Number);
var prev = SSI_GetValue('[% QuestionName() %]_r' + rows[0] + '_c1');
for (var r = 1; r < rows.length; r++) {
    var curr = SSI_GetValue('[% QuestionName() %]_r' + rows[r] + '_c1');
    if (curr < prev) {
        strErrorMessage = 'Error message.';
    prev = curr;
