// If the severity is changed to 1,2,3 AND prior severity value was not originally 1,2,3 then email Dev

code...

If severity.value= 1,2,3 AND onformopen severity <> 1,2,3 then
email.value-Dev

//If the status.value= red, blue, orange, then
email = Dev + what ever value they picked up in the assign to field

code...

ElseIf status= red, blue, orange, then
email= Dev + Assignto

// If you come intot he form and the severity is already 1,2,3 then remove QA from the email list

code...

Else onformopen serverity.value=1,2,3 then
email= Assignto


don't know if my coding is correct, some help would be great! :-)
