Hi xxbifferxx,
Below is a function that checks if Both Textfields match AND if they
have 2 Numeric Characters:

<html>
<script language="JavaScript">
function Check()
{
var pass = document.frm.txt.value;
var pass2 = document.frm.txt2.value;
//Check if 2 Passwords Match contain 2 Numeric Characters
if( (pass == pass2)&&(pass.match(/[0-9].*?[0-9]/g)) )
{	alert("Matched!");	}
else
{	alert("No Match");	}
}
</script>
<table>
<form name="frm" onSubmit="Check();">
<tr>
<td>Enter Your Password: </td>
<td><input type="text" name="txt" size="30"></td>
</tr>
<tr>
<td>Enter Your Password Again:</td>
<td><input type="text" name="txt2" size="30"></td>
</tr>

<tr><td>
<input type="submit" name="submit" value="Password Check">
</td></tr>
</form>
</table>

</html>

Please let me know if you have anymore questions.
Thank you.

Excellent! Big thanks worked well! I?d just like to know if I wanted
the pass.match(/[0-9].*?[0-9]/g)) != true, then alert("No Matched!");
how would I modify it as the one I mentioned doesn?t work.

<html>
<script language="JavaScript">
function Check()
{
//Retrieve 2 Textfield Values
var pass = document.frm.txt.value;
var pass2 = document.frm.txt2.value;

//Remove Spaces
pass  = pass.replace(/\s+/g,"");
pass2 = pass2.replace(/\s+/g,"");

//Match for 2 Numeric Characters in Password
var matched = pass.match(/\d.*?\d/g);

//Check if Two Passwords Match and contain 2 Numeric Characters
if( (pass == pass2)&&(matched) )
{       alert("Matched!");      }

if(!matched )
{       alert("No Match");      }

}
</script>
<table>
<form name="frm" onSubmit="Check();">
<tr>
<td>Enter Your Password: </td>
<td><input type="text" name="txt" size="30"></td>
</tr>
<tr>
<td>Enter Your Password Again:</td>
<td><input type="text" name="txt2" size="30"></td>

Try...

function checknum(pass)
{
numbers = new Array(1,2,3,4,5,6,7,8,9,0);
flag=0;

for(i=0;pass.length;i++)
{
   char = charAt(i);
   for(i=0;i<10;i++)
   {
      if(char == numbers[(i)])
      {
      flag++;
      }
   }
}

if(flag > 2)
{
  alert("This password has at least 2 numbers"); // OPTIONAL
}else{
  alert("Sorry, invalid entry"); // PUT ERROR EVENT HERE
}

}

if(pass1 == pass2)
{
checknum(pass1);
checknum(pass2);
}else{
alert("Passwords are not the same");
}

Not tested, so probably better waiting for one of the researchers
