Try changing

elseif
if ( !preg_match ("/^[a-zA-Z\s]+$/",$companyname)) {

To

elseif ( !preg_match ("/^[a-zA-Z\s]+$/",$companyname)) {

Side notes:

You could use a case-insensitive match by adding an "i" after the pattern delimiter:

elseif ( !preg_match ("/^[a-z\s]+$/i",$companyname)) {

Also, your pattern is going to turn away some perfectly acceptable company names such as AT&T, Phillips 66, Wal-Mart, etc.
