Custom data validation problem
I would like to validate cells according to the following rule ...
The cell can contain the following: A single zero "0" or a single period "." or a string of any length consisting of the letters R, W, B, L Eg all the following are valid 0 .. rrr bbbbb bbrrl l wrbblllrrrrbbbbbb The following are invalid 00 0r rrrbbbh ..rbl Is this possible using a custom validation? Thanks in advance. Neil |

How about:
Data|Validation|Custom: formula is: =OR(A1=0,A1="0",A1=".", SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(lower( A1),"r",""),"l",""), "b",""),"w","")="") all one line =substitute() is case sensitive. If you really meant rlbw--and not RLBW, then get rid of that lower() stuff. Neil wrote: I would like to validate cells according to the following rule ...

It's ok now, I have solved the problem, thanks to MrExcel
Here is how to do it if anyone is interested ... =OR(A1="0",A1=".",LEN(SUBSTITUTE(SUBSTITUTE(SUBSTI TUTE(SUBSTITUTE(UPPER(A1),"R",""),"W",""),"B",""), "L",""))=0) Neil "Neil" wrote in message ...

You got an answer here from Dave Peterson, do you want people to be able to
enter zeros? Then you should use his solution since the one you got will only prevent text zeros, not numeric zeros -- Regards, Peo Sjoblom "Neil" wrote in message ...

I havn't seen the reply here from Dave Peterson, but I already replaced the
"0" with 0 and it seems to work ok Thanks for your time Neil "Peo Sjoblom" wrote in message ... You got an answer here from Dave Peterson, do you want people to be able to enter zeros?
