Are you sure you read the setup guide?
Setup Guide:
Add the script to your collection via the SDN
Start up OSBot (or refresh your scripts list), then run the script
After the GUI (startup interface) shows up, enable human input by cycling the input button next to the pause/stop buttons
Select the rocks that you wish to mine via the game screen:
Make sure that the rock is not mined when you select it.
Make sure the rock tile is outlined on-screen and the rock data appears on the GUI.
You can remove rocks either by deselecting them in-game, or by manually removing them from the GUI. Currently selected rocks are highlighted in cyan.
Disable human input once you have selected your desired rocks (Settings>[check] disable input)
Configure the settings tab to your liking
If banking, be sure to select the closest bank to your mining location. Note that the banking code relies on the OSBot web-walking system, which can sometimes take a few seconds to calculate a route.
Start the script with the button at the bottom of the GUI
