jqgrid Error : Object does not support Property or Method 'Split' - forms

Question

I am using JQGrid v4.4.1 and MVC3.
When Selecting the 'Next Record' or 'Previous Record' icon on The JQGrid Edit Form, I get a Microsoft JScript runtime error: Object doesn't support property of method 'split'.
If highlights a block of code in the jquery.jqgrid.min.js module : var j=g.split(",")
Sometimes intellesense says that g=0, other times it's -2: I guess it's data related, but i cannot see anything that could be causing this!
I've tried to include a section of this module, including this call, but I'm struggling to make head nor tailof it!
Can anyone help me in determining the cause of this error?

After Oleg pointed me in the right direction (thanks Oleg!). I have managed to resolve this Error.
Using The jquery.jqgrid.src.js (much more readable) I managed to take an educated guess that the problem lay on a column in my Grid that was using a FORMATTER. I then noticed that even when loading the Edit form - the value for this column was not correct - and bacause The edittype was 'select', it was defaulting to the first item in the value list.
The Formatter would take the Value of the column (which could be either a -2, 0 or 1 in this case) and turn it into a gif for display purposes in the column. that worked lovely.
The UnFormatter, however, attempted to turn the image back into it's respective number (based on its title). I was then returning a numeric value ( ie. -2, 0 or 1). I needed to return a string value. (ie. '-2','0' or '1')
So, it seems that for Unformatters, you cannot return numeric values like this.
I have added the working code below for clarity :)
Working formatters
function EnabledFormatter(cellvalue, options, rowObject) {
var cellValueInt = parseInt(cellvalue);
switch (cellValueInt)
{
case 1:
return "<img src='#Url.Content("~/Content/images/tick.gif")' title='Enabled' />";
break;
case -2:
return "<img src='#Url.Content("~/Content/images/tick-grey.png")' title='Inherited' />";
break;
default:
return "<img src='#Url.Content("~/Content/images/cross.gif")' title='Disabled' />";
break;
};
};
function EnabledUnformatter (cellvalue, options, cell) {
var sTitle = $('img', cell).attr('title');
switch (sTitle)
{
case 'Enabled':
return '1';
break;
case 'Inherited':
return '-2';
break;
default:
return '0';
break;
};
};
Broken Unformatter Please note The lack of '' around the values returned. The EnabledFormatter is Unchanged
function EnabledUnformatter (cellvalue, options, cell) {
var sTitle = $('img', cell).attr('title');
switch (sTitle)
{
case 'Enabled':
return 1;
break;
case 'Inherited':
return -2;
break;
default:
return 0;
break;
};
};
