excel - Trouble pulling out any number from string -

-

i having trouble stripping numbers string. in excel, have many string fields may contain numbers. care number(s), rest of characters unwanted , discarded. number may in position, not set location.

for example: '2 catch basins' or 'catch basins x2'

i based code on so answer, can't seem work. error message 'application-defined or object-defined error'.

option explicit  function onlydigits(s string) string ' variables needed (remember use "option explicit").   ' dim retval string    ' return string.      ' dim integer        ' counter character position. '  ' initialise return string empty                       ' retval = ""  ' every character in input string, copy digits     ' '   return string.                                        ' = 1 len(s)     if mid(s, i, 1) >= "0" , mid(s, i, 1) <= "9"         retval = retval + mid(s, i, 1)     end if next  ' return return string.                          ' onlydigits = retval end function  public sub commandbutton1_click()  application.screenupdating = false  ' ----------------------------------------------------------------------------------------- ' strip numbers descriptions basins, guy wires, water meters/valves & pull box ' -----------------------------------------------------------------------------------------  dim counter integer 'index while loop dim fcode string 'variable column e, feature code dim fdesc string 'variable column f, descriptor   while cells(counter, 1).value <> ""  'while first column has data, keep looping fcode = cells(counter, 5).value   'populate feature code variable column e  if (fcode = "xcb") or (fcode = "xgw") or (fcode = "xwv") or (fcode = "xwm")     fdesc = cells(counter, 6).value     cells(counter, 6).value = onlydigits(fdesc) else      'do nothing end if   counter = counter + 1 loop   'finishes checking numbers within specific descriptors

can point me in right direction? appreciated!!

do while cells(counter, 1).value

here counter 0 range indexes start @ 1 hence error.
