phpGrid in CI Error

[eluser]dhall[/eluser]
I am trying to find a really good datagrid with lots of features; Search, Sorting, In-line Editing, Export to Excel, Hidden columns, Validation, etc.
The one I like so far is phpGrid but am getting an error.
Integrating it with CI I followed the below instructions which appeared to work mostly but am getting the following error. My page loads just find but the table does not show.

Error:
TypeError: jQuery(...).jqGrid is not a function
loadtext:"Loading phpGrid Lite..."

Install instructions:

I am still new to this whole development thing so any ideas how to fix would be great
If you know of an easier/better grid to use I am open to change.

Thanks!
