/^(?:[-()\d\s]|[Ee]xt\.)*$/
matches a series of (any combination of) only hyphen, left-paren, right-paren, digits, whitespace, or Ext. or ext. Updated: added the hyphen. Note that a hyphen, if it appears in a character class, must be the first listed character (so that it doesn't look like part of a character range).

THANKS!
My seeking help with making the ext. permissible actually solved two problems, as ikegami pointed out, my poor effort was not even doing what I thought it would!

Now if there only some way for perl to limit the number of characters in a text field, (not a text area and not the phone field)so they can't enter whole paragraphs in the title field............
