Lookup field script help: if, contains, count, &&

Lookup field script help: if, contains, count, &&

Can anyone see what I am doing wrong here? I am very new to this and can't work out why this won't work.

I am trying to say if the field "All_Competition_Teams" (multi-select lookup field) has more than one team selected which has "Cheer Sport" as the teams listed level AND another field "Primary_Competition_Team" (dropdown lookup field) also has a team that's level is listed as "Cheer Sport". Then do something.

if(Add_a_Students_Financial_Information[All_Competition_Teams.Level.contains("Cheer Sport")].count() > 1 && Primary_Competition_Team.Level.contains("Cheer Sport") == true)
{
input.testfield = 1;
}
