Validation with Regular Expressions

["Luckbox72"]

I am trying to validate data using regular expressions.
 here is  a copy of the code.

 <cfinput type="text" name="FQID_#ATTRIBUTES.FQID#_officer" width="36" 
validate="regular_expression" 
pattern="^\bna\b$|^\d*[0-9](|.\d*[0-9]|,\d*[0-9])?$" 
required="#ATTRIBUTES.required#" enabled="yes" message="0.0 to 100 or na, 
Required" value="#ATTRIBUTES.FQID_Response.Officer#" style="textAlign:right;" 
onchange="removeDash(FQID_#ATTRIBUTES.FQID#_officer);"/>                

 I do not get any errors but I am still able to enter anything I want into the 
text box.  I am trying to limit it to a number between 0 and 100 and excepts 
decimal amount.  It also needs to accept na if it is not applicable.  As it 
stands now I can enter anything.
