When do i use what tenses infrastructure of 場合は, in class I wrote for the example 病気になる場合は学校を連絡してください if you become sick please contact the school. However i was told this was incorrect and it should be なった not なる? In another example in the text book 学校を休む場合は、必ず連絡します. If you are going to be away please contact us. Why is this one not 休んだ like the sick one is なった?
