Mouse scroll WITHIN a data validation list & option macro assistance

So, if I read this right, is this code going to show the formula bar when the character length is greater than 50?

If I wanted to remove the formula bar altogether (still trying to figure out whether I want to keep it or not), could I set this to 0 so the formula bar never shows while using the tool? I realize every user has different options they can select for the formula bar, but I thought this would eliminate it completely without having to go to each PC and remove it?

Edit: It will show it when it's less than 50, not greater. My fault. I implemented the code and found out for myself. I'm finally getting the hang of this. I just wish I knew what great options I could add to this tool. I'm really trying to help the company I work for, and not only that, but my my job easier.

And thank you, again, for helping me.
