Question : access 2007 - invalid procedure call

I have a query:
SELECT
network_contact_name,
First(Left(network_contact_name,(InStr(network_contact_name,' ')-1))) AS FirstName,
First(Mid(network_contact_name,(InStr(network_contact_name,' ')))) AS LastName,
First(network_contact_number),
(First(Mid(network_contact_name,(InStr(network_contact_name,' '))))+", "+First(Left(network_contact_name,(InStr(network_contact_name,' ')-1)))) AS lastfirst
FROM local
WHERE network_contact_name like  "*HELP*" and  (instr(network_contact_name,'/') =0) and status in ("DEAD","DISC PEN","DISC NET")
GROUP BY network_contact_name;

If I remove from the WHERE clause "network_contact_name like  "*HELP*" and " and run it, I get the error, otherwise it runs fine.
anyone know why?
thanks much.

Answer : access 2007 - invalid procedure call

ok, so looks like I had a few things i did to get it working.
stripped all the firsts out and that seems to be a key...tried without concat part
changed my where a little....then added the some of the first stuff back in...

SELECT
FIRST(network_contact_name),
FIRST(network_contact_number),
customernumber,
status,
instr(network_contact_name,'/') ,
Left(network_contact_name,(InStr(network_contact_name," ")-1) ) AS FirstName,
Mid(network_contact_name,(InStr(network_contact_name," ") ) ) AS LastName,
(Mid(network_contact_name,(InStr(network_contact_name," ") ) )  & ", " & Left(network_contact_name,(InStr(network_contact_name," ")-1) )   ) AS lastfirst
FROM local
WHERE  (instr(network_contact_name,'/') =0) and status not in ("DEAD","DISC PEN","DISC NET")
GROUP BY network_contact_name, CustomerNumber, status, network_contact_number
Thanks to all who participated.
