If they are leading spaces after the 0 is removed, try using
TRIM() after the 0 is removed, otherwise if they are
leading/trailing spaces before the 0 is removed, try using TRIM()
before you remove the 0. If they are just spaces within the string,
just replace spaces with nothing.
<cfset PhoneNo = trim(removeChars(Send.Phone,1,1))>
--or--
<cfset PhoneNo =removeChars(trim(Send.Phone),1,1)>
--or--
<cfset PhoneNo =removeChars(replace(Send.Phone, " ", "",
"all"),1,1)>
