 * Hi, I’m trying to create a new text validator. I need exactly 6 alpha numeric
   characters. I already have ‘max-characters’ set to 6 in my form settings but 
   this allows less than 6.
 * I’ve tried
 *     ```
       /^\[a-zA-Z0-9]$/
       /^\[a-zA-Z0-9]{6}$/
       /^\[a-zA-Z0-9]{6,6}$/
       ```
   
 * which have all been accepted as correct regex codes, but each one gives me my
   error message. Any ideas? Thanks.

 * You don’t need to escape the first square bracket.
