loop stop executing after executing nested if statement

I wrote a nested loop like below:

   for i = 1:m
      do something;
      for j = 1:n 
        do something;
        if conditionIsTrue
          do something;  %without continue or break
        end
      end
    end

But the loop ends after the first time the condition in if statement is executed and return incorrect result, I tried to modify the code as below:

    for i = 1:m
      do something;
      for j = 1:n 
        do something;
        if conditionIsTrue
          do something;  
          continue
        else
          continue
        end
      end
    end
The problem's still there. How can I deal with this problem?
