The issue you are running into is a combination of the item number not being the maximum number of characters and the item format being multi-segmented. I was able to duplicate what you have if a portion if the first segment has leading blanks. If the entire first segment of the item number is blank, that item code is read into Quik Link correctly.

The #keyvalerr# is returned by Quik Link if the program cannot recognize the 'key' in the formula; in this case the Item Code. This is something that exists is the current shipping version of Quik Link and will have to be addressed by Development.
