Nested ifelse statement with strings

I am having some trouble debugging my nested ifelse statement.

Praxis_Dat$Result <- 
  ifelse(Praxis_Dat[, 22:24] == "Pass", "Pass",
         ifelse(Praxis_Dat$`Met Praxis I Req by SAT` == "yes", "Exempt", "Not Pass"))

It runs the first part just fine, then won't run the second ifelse statement. I have tried reversing the order of the statements. I have several functions that work similarly. I don't understand why the second half is not running like it's supposed to.
