Hi everyone,
I have a problem validating mutiple results using the same input text.
For example,
I use a for loop to display 5 rows of input text
User is require to key in a value in each of the 5 rows
But when i try to validate the 5 rows to check for empty field
The javascript is only able to validate only 1 row of result
Even if it is 10 rows, it only can validate 1 row of result
In other word, the javascript is only able to validate one row of result at any
one time.
How can i validate all the rows using javascript?

Below is the code that i am doing

<form name="main_form" method="post" target="_blank" action="process_coa.asp" onsubmit="javascript:return checkform(this);">
 
 
<% if product = "DBE" then %>
 
<tr>
    <td align=center width=100 class=tableborder>
    <font class="font"><b>MFG<br>LOT#</b></font>
    </td>
 
    <td align=center width=100 class=tableborder style="border-left:0px">
    <font class="font"><b>Loading<br>Date</b></font>
    </td>
 
    <td  align=center width=100 class=tableborder style="border-left:0px">
