Counting distinct values with two conditions

I am trying to count distinct items that fit two conditions, but I'm getting back an error.

Here is the formula I was trying:

=COUNT(DISTINCT(COLLECT({My Sheet Range 1}, {My Sheet Range 2}, CONTAINS("SEA", @cell), ({My Sheet Range 3}, CONTAINS("In Progress", @cell)))))

If I remove the second condition or use only the second condition it works, but I only want items that contain BOTH "SEA" and "In Progress".
