Unable to get property 'tcontrol_setvisible' of undefined or null reference

Mario Enríquez Open Consult	Hi folks, I've run into some trouble with an EWB project with one single form. I'm getting the following message: 'Unable to get property 'tcontrol_setvisible' of undefined or null reference' I've searched for this error the forum but no solution appears to apply. When the form is shown everthing is ok, no error shown. As soon as I click on one of the Tabs the error above is display. There is no event code related to this action by the way. I would really appreciate any help on this subject. I have an screen shot of the error, and if anyone is interested I could share the project... Regards, Mane Attachments: 003_planificacion.jpg

Hmm, the solution will be to use the Browser debugging tools. I recommend Chrome, and enable the "pause on handled exceptions" option. Then you will find out exactly where it is failing, and you will go "Duh!" and all will make sense. 8-) -- Matthew Jones

If you want to email me the project, I can take a look and tell you what's going on. Tim Young Elevate Software www.elevatesoft.com
