Forum OpenACS Development: Re: show variable assigned value

I finally got it working well 

Although i still don't see where the error was before,  lappend had errors somehow 

foreach {category_id category_name } [videos::get_categories -package_id $package_id] {
    ns_log Notice "ITEM: $category_id - $category_name"

    lappend list_elements cat_${category_id} [list \
          label [category::get_name $category_id] \
          display_col cat_$category_id]

 
then error.log  shows
