Why this multiple criteria with INDEX MATCH is not working

I am following this great article to practice INDEX MATCH with multiple criteria but the formula I wrote is not working. I am using the example provided in the article to practice (downloadable without signing up).

What is wrong with my forula?

=INDEX(Table1[Price], MATCH(1, ([@Item]=Table1[@Item]) *( [@Size] = Table1[@Size])*([@Color]=Table1[@Color]),0))
