DDocName in the resultset gets higher preference than local variable: unable to set dDocName in the binder using Idoc Script

Question

Hi,
I have the following code built using idocScript
<$dDocName=variableName$>
<$executeService("DOC_INFO_BY_NAME")$>
Note: variableName has value of contentID for which "DOC_INFO_BY_NAME" has be executed.
When i execute this, i see that DOC_INFO_BY_NAME is getting executed for previous content ID that "dDocName" was  holding. In other words, following assignment
<$dDocName=variableName$>
Is not taking effect.
I think the value is not getting updated in the binder. How do i correct this.
This is little urgent, Any help would be greatly appreciated.
Thanks and Regards,
Seshan K.

This issue is seen when we are accesing the page that list down all the blogs postings along with author images.
Step 1: Execute the search to fetch blog postings:
         Associated IdocScript: <@dynamichtml dv_blog_landing_page_postings@>
Step2: Loop through result set and build blog listing
          Assocaited html fragment: <$include dv_blog_post_searchresults_landing_html$>
     Sub step2: Fetch image of blog Author when displaying the blogs listings
               Associated fragment: <@dynamichtml dv_get_blog_author_image@>
               Note: Issue is seen in this block
Following is the actual logic. All the calls to the display fragments are in bold. All the comments are in italics.
