whoops didn't read the full message.
here is where you go wrong i think :)

location will give the location of the start of "_new"
you want the next char not the position of the "_"
then: newstring_withnum_tostr = words1.substr (location + x, 1)
words1.replace (newstring_withnum_tostr, cint (newstring_withnum_tostr) +
1 )
check it:
response.write (words1)
