Vlookup and Concatenate or INDEX/MATCH and Concatenate

Hi folks,

I have the following in Sheet1

Data 1 Data 2
A Alpha
A Beta
A Charlie
B Delta
B Echo

And this in Sheet2

Data 1 Result
A Alpha-Beta-Charlie
A Alpha-Beta-Charlie
A Alpha-Beta-Charlie
B Delta-Echo
B Delta-Echo

Columns As in both sheet are identical and I'd like to concatenate as shows in result column of 2nd sheet.

Thanks
Khan

Works like a charm, thank you so much
