Hi,

Checkout this FAQ for debugging, and let me know the ajax response if not solved.

Few considerations before use

1) include the jqgrid_dist.php file before any thing rendered to output.
2) Check the ajax response of grid,

Use firefox->firebug->net->ajax-call of grid->response. You will see the output there, in case of any error. It should be proper JSON format data in order to render grid

Review this tutorial for '[debugging with firebug](https://phpgrid.desk.com/customer/portal/articles/926266)'.

To enable debugging errors,

1) Turn errors on. Goto jqgrid_dist.php make it 'on'

ini_set("display_errors","on"); // changed from off to on

Hi,

Thanks for your quick answer! I debugged the program as you suggested and the response tab of Firebug gave me the following output:

Couldn't execute query. Incorrect integer value: '' for column 'Budget'…

After seeing this error message I added the following property to the column Budget:

$col["isnull"] = true;

This didn't change the error message in Firebug. Then, I added the folling property to the column Budget:

$col["formatter"] = "number";

Now al NULL values in the column are automatically set to 0 and changes in the relevant rows are possible. But the NULL values should not be set to 0, this gives a wrong interpretation!

How can I solve my problem?

Thanks!
Charlotte

Hello Charlotte,

This issue is fixed in latest build, which is available as paid version. Unfortunately, the free version is little outdated, and need a build. If you wish to buy in near future, i can send you package now and then you can pay when you have completed the testing.

Thanks
