/* GetItemRank ( item ; ValueList ) by Fabrice Nordmann v.1.0 Aug 29th 2006 returns the index of an item in a list GetItemRank ( 3 ; 5¶3¶7¶9 ) = 2 based on cf_getElementNo by Klemens Müller, www.klemenso.de cf_getElementNo( SearchString ; ElementList ) */ Let( [ spos = ¶ & item & ¶ ; clist = ¶ & ValueList & ¶ ; fpos = Position ( clist ; spos ; 1 ; 1 ) + Length( spos ) -1 ; flist = Middle ( clist ; 1 ; fpos ) ; out = ValueCount( flist ) -1 ] ; Case ( PatternCount ( clist ; spos ) ; out ; 0) ) Click to copy

[EDIT :
I don't use this one anymore, since PositionValue, by Geoff Wells ( http://www.briandunning.com/cf/62 ) does the same, with more features.]

I found Klemens Miller's function cf_getElementNo very elegant, but I needed it to return the rank only if the item was matching exaclty an item of the list, and not if it was only found (= vs patterncount ).
Function returns 0 if item is not matching any list value.
