I have a select list field and a regular text field .... I want the text field value to be set based on the user selecting a value from the select list .... the select list displays a string value and the 'return value' is a number. I have looked on the forum and tried a number of aproaches that have been posted but cannot get anything to work ..... here is my code below ....

**********************************************************************************

code below is in the html header for the page:

<script language="JavaScript" type="text/javascript">
<!--

htmldb_delete_message='"DELETE_CONFIRM_MSG"';

//-->
</script>

<script language="JavaScript" type="text/javascript">
funtion set_abcd_id()
{
function getVal(item)
{
if (document.getElementById(item).value != "")
return parseFloat(document.getElementById(item).value);
else
return 0;
}
document.getElementById('P1_ABCD_ID2').value = getVal('P1_DETAIL_ABCD_ID');
}
</script>

p1_detail_abcd_id is the select field; p1_abcd_id2 is the regular text field;


******************************************************************************************

code below is in the html element attributes for the select list field ...

onchange="set_abcd_id(html_SelectValue(this.value));"

i also tried

onchange="set_abcd_id();"

but nothing works at this point.

I would really appreciate someone helping me understand what I am doing wrong ...
