Hello tony, thanks for the input.

f & q are text variables that contains the values i want to send.

Btw i've updated my jqgrid.js and included all the module (im still in a test environnement so its not a problem) and know, I dont get the error anymore but nothing is posted.

Heres the complete code :

Dear tony,

i tried to change the name of the mtype option without success.

I started a new page and did the exact same grid as before and this time… it worked !

I have absolutely no clues of what was the problem… but everything works like a charm now.

Thanks a lot for your dedication & your hard work.

Regards,

M.
