Script Dictionary Not Matching

Good Day,

I'm learning (experimenting) with the Script Dictionary, but I'm unable to use the Exists Method (probably the way I want it to work). I'm using the script dictionary like a lookup, but script dictionary is not giving me unique items, and it is not indicating the items exist in the dictionary.

Sheet1 collects the items for the script dictionary, and Sheet2 should give me the result after running the macro.

I've uploaded a file with the test data.

I'd appreciate your help assisting me in understanding this area of VBA.

Thanks,
Xrull
