SQL Exists returning errors

Question

So I have the following query:

select *
from ft, pn
where exists (ft.vendnm like '%rocha%' and pn.fno = ft.fno);

Where I only want the results that respect the conditions inside parenthesis. What SQL Server tells me is:

Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.

And I'm not getting what's wrong with this.

The whole code for context:

select 
x.Num,
x.Cliente,
x.Zona,
sum(x.valor_1) as Valor_1,
sum(x.valor_2) as Valor_2,
x.Vendnm,
