Field with numbers and characters get nan

[edgarv]

Hello,
I have the code below
where the "day" field is coded as digits and numbers, for example
Day Code
1 = 1
2 = 2
3 = 3
4 = 4
5 = 5

but after 5
it the code changes to a letter
6 = A
7 = B
and so on, if the user types a number I have no issues but if the user types a letter then I get "nan", is there a way to handle this so I get the correct code?
<code>
<script type="text/javascript">
function generateFullName()
{
document.getElementById('joint').value =
document.getElementById('rnd').value + document.getElementById('usmade').value +
document.getElementById('year').value + document.getElementById('month').value + + document.getElementById('day').value;

}
</script>




<td bordercolor="#000033" bgcolor="#FFFFFF"><div align="center">
<input name="joint" id="joint" type="text" size="15" maxlength="100" onChange="javascript:this.value=this.value.toUpperCase();" />
</div></td>
</code>


In advance, thank you for any help or pointing me in the right direcction

suspect its trying to do arithmetic calculations and gets an issue with character, you may need to investigate Casting to ensure that the calculation is done as Strings.
