The actions that we perform are: 1. Define a boolean variable as global in the page. 2. I define a field on the form and leave it as hidden. 3. Sortie avec modification (onchange) (navigateur) a. I set the variable Boolean to TRUE b. I set the hidden field to 1 4. Click (onclick) Output Pin (navigateur) a. The boolean variable and kept hidden field value of 1 which I have put in point 3. 5. Click (serveur) AJAX not activated a. Neither fields (boolean and hidden) maintain the value 1, so I can not update the DB when any of these fields is set to 1 because I detect any change with an IF statement and the fields always have value zero. The problem is that I can not share variables between the browser and server. Does anyone know how to do a process like this? Thanks in advance. Jordi How I can do this ?.30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/50135-wb19-variables-browser-and-server/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)guestpcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/50135-wb19-variables-browser-and-server-50147/read.awp28 Jan 2015 12:55:00 ZHi Jordi, That's correct.
