Hi What you've written doesn't match the description you gave. As a regular expression "([0-9][A-Z][a-z][-_.'\ ])" means a digit followed by an uppercase letter followed by a lower case letter followed by (hyphen or underscore or mid-dot or single quote or space). This is a total of four characters only. Is your string only supposed to be four characters in that format? I had assumed from your original post, that you wanted a variable length string, that could only contain alphanumeric characters plus hyphen, underscore, and single quote (I missed the space). All of which in any position. If this is not the case please describe exactly what it is you're trying to achieve.
