Specify conditions in Formula editor

How Can i specify two conditions in a formula Editor

I'm trying to supress the field in the report based on 2 Conditions
{SeaFarer.MigraineCandidate}=False; ====> First condition

if {@check}='True' then =====> Second condition
true
else
false

Code:

---

If {@Check} = 'True' And {SeaFarer.MigraineCandidate}=False Then
 True
Else
  False

---

This should also work

{@Check} = 'True' And {SeaFarer.MigraineCandidate}=False
