Hi, thanks for asnwering.
I just started a new project from scratch and all is fine. HOWEVER, I had been reading extensively about creating dashboards and was advised to use a responsive design in html5 + css etc... but still use php and mysql. ie: Someboady advised me to stop using flex as that would not be a viable solution for tablets and mobiles and the flash player is not supported. I know we have the AIR run time but this is supoposed to be a dashboard running in the browser so teachers can log in and check out kids results. I don't know if you have any opinion about this.
