Data Validation used with VLookUp function

[Mekinnik]

How can I use the data validation tool in a column on sheet1 based off of
data from sheet 2 a1-a50(I do know how to use the tool), where if you choose
say 'xx'(the value from a1) from the drop down list the function will return
the value from sheet2 b1 instead of a1.

You need to have 2 columns in the sheet 1. Fitst (a1) will be the result
selected in the drop down, the second (b1) will be your vlookup that will
return your value.

Also, on data validation in order to read the data list from sheet 2 the
range has to be labled for example 'Range1". Then in the validation box you
need to call up that RangeName
