Missing custom basket field values?

[gsam]

On a product page with the add to basket button I'm capturing a screenshot. The screenshot's ID and NAME are passed to the basket page(g.newimage_id, g.newimage_name). On the basket page if there is a value for the ID I save it and the NAME to custom basket fields. At the bottom of the basket contents I display all custom basket fields. The problem is that if the Write_Basket statement is executed then the display all custom basket fields forgets everything except the field it just saved. For example if I have two items in the basket when I add the third the only custom basket fields that show any values belong to the third item.

If I go to the store front and back to basket, the Write_Basket would not be executed and then all the custom basket fields appear.

This is the code I'm using. It's located at the bottom of the basket contents.

<mvt:comment>if adding a product to the basket save the ID and NAME values</mvt:comment>
  <mvt:if expr="g.newimage_id EQ '' ">
  <mvt:else>
    <mvt:item name="customfields" param="Write_Basket( 'id' $ g.newimage_id, g.newimage_id )" />
    <mvt:item name="customfields" param="Write_Basket( 'name' $ g.newimage_id, g.newimage_name )" />
  </mvt:if>

<mvt:comment>display all custom basket fields</mvt:comment>
<mvt:item name="customfields" param="Read_Basket( '' )" />
<mvt:foreach iterator="basket" array="customfields">

<mvt:comment>use the name field to call the saved image</mvt:comment>  
<mvt:if expr=" 'name' CIN l.settings:BASKET:code ">
    Code:&mvte:basket:code; - Value:&mvte:basket:value;<br/>

    <img src="&mvt:global:domain:base_url;screenshots/&mvte:basket:value;" style="max-width:500px;"><br/>
  </mvt:if>
</mvt:foreach>

Anyone see a reason for the loss of data when writing to a custom basket fired?
