excel - Determining the number of matches to a "Find" on a given range -

-

i have macro selects particular range , find number "0" on it. know how many times "0" appears in range i've selected can create variable equal number. how can set variable equal number of times find returns match query?

activecell.select selection.offset(0, 1).select item = activecell.value sheets("lights").select rows(3).select selection.find(what:=item, after:=activecell, lookin:=xlvalues, lookat:= _     xlpart, searchorder:=xlbyrows, searchdirection:=xlnext, matchcase:=false _     , searchformat:=false).select      q = activecell.row()      z = activecell.column()     range(cells(q, z), cells(72, z)).select     selection.find(what:="0", after:=activecell, lookin:=xlvalues, lookat:= _     xlpart, searchorder:=xlbyrows, searchdirection:=xlnext, matchcase:=false _     , searchformat:=false).activate

so if there 7 instance of 0 on range want set variable m= 7

m = worksheetfunction.countif(selection, 0)

or partial matches:

m = worksheetfunction.countif(selection, "*0*")
