Works OK for me on your posted sample data.

Are there any non-numbers within the ( )?

May (x)
Peter (10A)

There may also be unseen whitespace characters like HTML char 160 at the end
of the string.

May (17)<char 160

Try one of these in C1:

=--SUBSTITUTE(LEFT(A1,FIND(")",A1)-1),B1&" (","")
=SUBSTITUTE(LEFT(A1,FIND(")",A1)-1),B1&" (","")

If there are non-numbers within the ( ) then the 1st one will still return
an error.

The 2nd one will return whatever's inside the ( ) as TEXT (even if it's a
number).

Dear Valko,

B1 works but C1 only returns an #VALUE!

Try these...

B1:
=LEFT(A1,FIND(" ",A1)-1)

C1:
=--SUBSTITUTE(MID(A1,FIND("(",A1)+1,10),")","")
