Thanks Ray. I do not know if I explained clearly. I have opened and modified the rsobj.php file several times and changed line 12 of:
$ this-> Debug = false;
to
$ this-> Debug = true;
and backwards. That is to say:
$ this-> Debug = true;
to
$ this-> Debug = false;
And the result has been the same: when clicking the submit button of my form, the application window remains blank with the message:
There is an error in your SQL syntax.
Thank you
