jQuery Grid Plugin - jqGrid

Hi All

I am using a grid and have enabled cell editting.

Does anyone know how to alert returned values from an ajax call ?

My Grid allows me to call my Ajax function and my function then returns a calculated value.  I am just unsure how to

pick up and alert this value from within the grid. 

I am using the following standard settings :

....

,cellEdit: true

,cellsubmit: "remote"  

,cellurl: 'fnt_myFormEdit' 

,

cellEdit: true

......

Many thanks for any help.
