Amazon cck field returns empty when used in flexifield (cck)

My problem started when I included the amazon cck (asin module) in Flexifield. Even if I enter a valid ASIN, it does not do anything and does not display anything. I found out there was inaccuracy in the field name. I was able to solve it and created a patch. Please let me know if there would be complications in the adjustments I made.

thanks!
