Thanks for your Help:
What I am trying to do is Modify this W3School's example code
so that I can DragDrop Multiple Divs
Rather than just DnD 1 Div .
W3Schools online HTML editor
My code has changed a bit from above code ,
now using DIVs instead Images .
The 1st script figures out which DIV was Clicked-on .
The 2nd script then Drags and Drops the Clicked-on DIV .
I am trying to get from 1st script
to function dragElement(holdTargetId) which is in 2nd script .
It never gets to:
function dragMouseDown(e)
function elementDrag(e)
function closeDragElement()
Thanks for your Help...
