Hi,
Is it possible to use AND in an eval if statement.. for instance if(volume =10, "normal" if(volume >35 AND <40, "loud")) and so on.. I would like to add a few more if's into that as well..Any thoughts on how to structure it?

Yes you could do that with if, but the moment you start nesting multiple ifs it's going to become hard to read.
Why don't you use case instead?
eval whatever = case (
volume = 10, "normal",
volume > 35 AND volume < 40, "loud",
1 = 1, "default rule"
)

You can use case statement instead the syntax is
case (condition , TRUE, FALSE)
You can have nested case statements as well for eg.
|index=main | eval system=case(isnotnull(dest) AND dest!="unknown",dest,isnotnull(src) AND src!="unknown",src,isnotnull(dvc) AND dvc!="unknown",dvc,1=1,"unknown")
