I would like to know how to write the syntax to test for
1. age44 or 2. Seniority is 9 and by determining the answer to that
3. Arsenic exposure 4.9
4. Cadmium exposure 2.4

If 1. is true or 2. true then I need to check 3. and 4.
if 1. is true or 2. is true and 3 and 4 are false then ?
if 1 or 2 is false and 3 or 4 is false then something else

would I use and or /and condition. The way I wrote my syntax the or works
but the and does not. Any clues on how to write the syntax to check for all
4 conditions?
