Hi there charlee,

does this help at all...

<script type="text/javascript">
var matches=[];
var strings=[
  'Today is Saturday 24th', 
  'No. 120 Ridge Road', 
  'Sunday 16th December',
  'This is Webmaster World',
  'I am 43 years old',
  'I moved house on the 30th',
  'My salary is £20k per annum'
  ]; 
for(c=0;c<strings.length;c++) {
if(matches[c]=strings[c].match(/\d{1,}\.{0,}\d{0,}/)){;
 alert('string '+(c+1)+ ', contains the number...\n\n  '+matches[c]);
 }
else {
 alert('string '+(c+1)+ ', contains no numbers');
 }
 }
</script>
