Re: Funtion to clean up strings?

Wow, that was fast
THANKS :)

now ... lets get more complicated.
Phone numbers are entered:
0123/4567-89 national number
0049/123/4567-89 the same number
+49/123/4567-89 still the same number

should come out as 0123456789 to search in this column.
"0049" and "+49" --> 0

while international numbers
+33/123456789
0033/123456789

should come as
+33123456789

I fear the hard part is that international codes have 1-3 digits :(

Andreas
