Need help with an if statement

I am very new at writing Javascript and am having a lot of fun learning.  I need some help with one that has me out in left field.

I have a negative (or a positive) value in a cell.  Generally, the value is going to be negative with only a few exceptions in the other direction.  What I want to do is make two different electronic signatures appear from their current invisible status, BUT only with different values in the calculated cell.

Right now I have the following script...

if (this.rawValue < "1") {

     AcctEsig.presence = "visible";

     } else {

     AcctEsig.presence = "invisible";

}

I need this one to  make the AcctEsig object appear actually when the value is between -1 and -99

I will need the next one to open the account manager's Esignature if the value is -100 or even less.  Therefore as one can see, I'm thinking I can get away with 2 separate scripts, BUT I know that there may be one that can present both eSig blocks but at the designated different times.

Any ideals?

Thank you so much ahead of time.
