jQuery Grid Plugin - jqGrid

I'm new to JQuery and all of it's wonderful plugins such as the Grid. I recently developed a website and I use JQGRID for all of my admin pages. I originally developed the website using Chrome and started the lovely process of checking cross-browser compliance. IE seems to behave properly besides some CSS differences. When using Firefox however, all of the pages seem to render properly, but when trying to perform any updates on the admin pages, whether it's adding a new record, updating an existing record or even deleting a record, I keep getting the error in Firebug's console window "Command text was not set for the command object".

My server side pages are using classic ASP, and from what I can tell by looking at Firebug's console window, anything that is passed to the ASP page within the url or editurl is getting requested properly. But anything that appears in the POST tab of the console window such as the fields that are being updated or the default ID or OPER are not getting requested on the ASP page, therefor causing the above mentioned error because I do not set my SQL until I determine what value was passed in for OPER.

Hopefully this makes sense. It seems like there is just something I need to do slightly different with Firefox because it works fine in IE and Chrome. I'm using JQUERY 1.5.2 and JQGRID 4.0
