Please check if you have the following lines in your script code:
tab0.MouseWheel (0, 0);
If so, just delete them and try to play it again. Looks like there’s a bug when this line is recorded additionally to the correct one with valid coordinates.
You can also provide the script itself as a file with “dmuv” format so we can check on our end. You can do it from within EveryStep Scripting Tool clicking “Save Device” button in the bottom-left corner and then selecting “Save to Local Machine” option. Also, it would be great to have steps explanations so we can understand what you’re trying to implement.
