Google Sheets: carry value from one sheet to another

I have 2 worksheets in 1 file. I want to bring the value from 1 sheet to another. I only want the value IF it has the name of someone.

Sheet 1

+---+-------+--------------+|   |   A   |       B      |+---+-------+--------------+| 1 | Names |    Values    |+---+-------+--------------+

Sheet 2

+---+---------------------------------------------+----+|   |                      A                      |  B |+---+---------------------------------------------+----+| 1 | Value from B1 If A1 matches a specific name |    |+---+---------------------------------------------+----+

I've tried =if(RegexMatch) but it says it contains 2 arguments

Any suggestions?
