Color select/erase tool help

[BobMoyer]

Just downloaded/purchased DesignerPro X and do not understand how to use this tool. I followed the instructions in the help file (as well as an old man can!) and cannot get it to work. For instance, I cannot get the color tolerance/fade controls to move off of 20/25% respectively. I know it is my fault so please be gentle. A step by step would greatly be appreciated. If you specify which photo you are using in the Design gallery, I will follow along. Thank you.

Bob

Edit: I have no idea how I posted this question to the wrong forum group....should have gone into the Graphics Chat area....boy am I having a bad day or what?
