Error      2      'System.Web.SessionState.HttpSessionState' does not contain a definition for 'Item' and no extension method 'Item' accepting a first argument of type 'System.Web.SessionState.HttpSessionState' could be found (are you missing a using directive or an assembly reference?)      D:\inetpub\wwwroot\OmegaLove\Controls\ctrlBreadCrumb.ascx.cs      102      29      OmegaLove

This is due to:
Session.Item["HASH_OF_CRUMPS"] == null and  _crumbList = Session.Item("HASH_OF_CRUMPS");
There is no Item for Session
you should get session items like this:-- Session["HASH_OF_CRUMPS"]

if (Session["HASH_OF_CRUMPS"] == null)
                {
                    _crumbList = new SortedList();
                    Session.Add("HASH_OF_CRUMPS", _crumbList);
                }
                else
                {
                    _crumbList = Session["HASH_OF_CRUMPS"];
                }

Error      7      A local variable named 'level' cannot be declared in this scope because it would give a different meaning to 'level', which is already used in a 'parent or current' scope to denote something else      D:\inetpub\wwwroot\OmegaLove\Controls\ctrlBreadCrumb.ascx.cs      154      26      OmegaLove

This is due to declaring "level" variable to times...:
           
 1 here --->         short level = 0;
            ArrayList removalList = new ArrayList(_crumbList.Count);
 2 here--->    foreach (var level in _crumbList.Keys)
            {

So change either of the variable name eg. level1 and level2

Error      8      Operator '>=' cannot be applied to operands of type 'object' and 'short'      D:\inetpub\wwwroot\OmegaLove\Controls\ctrlBreadCrumb.ascx.cs      156      22      OmegaLove

That is due to type mismatch :
----->  foreach (var level in _crumbList.Keys)
            {
                if ((level >= _level))
_level is short while level is object
So try like this:
foreach (short level in _crumbList.Keys)
            {
                if ((level >= _level))
