Can someone help me with this - it is not calculating if over 99 only if over 49 IF({Miles}>49,"0.10", IF({Miles}>99,"0.15"))

I can not get this formula to work.... is it completely wrong or am I missing parathesis?  IF({PMID}=“BathJR”,"Jason R",IF({PMID}=”BathSS”,“Stuart S",IF({PMID}=”BathBL”,“Brian L",IF({PMID}=”ODLBL”,“Brandon C",IF({PMID}=”WINBL”,“Evan V",IF({PMID}=”ODL...

How can I create views for several collaborators? I do not want it for my entire team just select users.

Here is my formula IF({Dept} =Bath, “8.5”, IF({Dept} =Win, “10”, IF({Dept} =ODL, “0” ) ) ) My objective - if field “Dept” is Bath then 8.5, if it is Win then 10, if it is ODL then 0
