I have a variable on lead: var activityNumber = "1";

I want to increment this number each time a new activity is created. To do this I have want to call this variable on the activity and increment, but I am not able to recall the variable. I have tried alert (window.top.opener.activityNumber); and just window.top.activityNumber but get error message that the variable is not defined.

How can I get the variable and increment it from activity to lead.

Many thanks for help!

Hi Martin,
Why you are not creating real time workflow . I think this will be easiest way to do this using workflow .

Please have a look below reference where I have answered--

In addition you can try with this -

var no = window.parent.opener.Xrm.Page.getAttribute("new_activityno").getValue();
var incrmentNo = no + 1;
window.parent.opener.Xrm.Page.getAttribute("new_activityno").setValue(incrmentNo);
