hi there, I have build one site about online appointments of pasients for dentist. i would like to create such a event scheduler like http://www.dhtmlx.com/docs/products/dhtmlxScheduler/sample_basic.shtml but additionally with copy and paste events.
the original program is not web based.
the working of that program is below.
