=SUMPRODUCT(--(A3=ALB!$A$2:$A$2000))

I have the above formula over 1000 lines which I need to sort the result
ascending/descending of those 1000 lines some point to different worksheets
so when I sort they no longer point to the correct worksheet. How do I use a
sumproduct to reference all worksheets (up to 17 worksheets) incidently all
will have the same range A2:A2000 just different worksheet name.

ALB.UNKN (worksheet alb)
BAT (worksheet bat)
BAT.001 (worksheet bat)
BLA (worksheet bla)
BLA.001 (worksheet bla)
CRE (worksheet cre)
CRE.001 (worksheet cre)

I'm sure they will be a solution quicker than I typed this request.
Thanks
Bec
