Dynamic Form Values -Outputting

I have a form that submits to itself like this

<form action="" method="post">

<table >

   <tr>

  <td width="50"><input type="checkbox" name="client_id_C" value="#client_id#"   ></td>

   <td  width="50"><input type="text"  name="#client_id#_Fee"  value="">  </td>

</tr>

</table>

</form>

The client_IDs are 101,102,103 etc

So when I fill out the form I get form values like this

101_Fee = 1000

102_Fee = 2000

103_Fee = 3000

I also get a list of the client_id's like

client_id_C = 20864,21238,21284

My question is once the form is submitted and the form reloads.

I want the fee values to populate the #client_id#_Fee text boxes, like this

<form action="" method="post">

<table >

   <tr>

  <td width="50"><input type="checkbox" name="client_id_C" value="#client_id#"   ></td>

   <td  width="50"><input type="text"  name="#client_id#_Fee"  value="#(#client_id#_Fee)#">  </td>

</tr>

</table>

</form>

Obviously what I have in red doesn't work

The problem is how do I code to get the value?

For example

I want the value for client_ID 101 to be 1000

Like this

<form action="" method="post">

<table >

   <tr>

  <td width="50"><input type="checkbox" name="client_id_C" value="101"   ></td>

   <td  width="50"><input type="text"  name="101_Fee"  value="1000">  </td>

</tr>

   <tr>

  <td width="50"><input type="checkbox" name="client_id_C" value="102"   ></td>

   <td  width="50"><input type="text"  name="102_Fee"  value="2000">  </td>

</tr>

</table>

</form>

What code goes in the value where the red text is.?

Because the variable already contains # tags.
