🔵 GSE.lua file:
Please provide your GSE.lua file or the export string for the specific macro that is causing an issue.

• To find the GSE.lua file:

1. First, make sure you have enabled the "File Name Extensions" checkbox in Explorer (View tab)
2. Browse to C:\path\to\wow\_retail_\WTF\Account\YourAccountName\SavedVariables\ or /path/to/WoW/_retail_/WTF/Account/YourAccountName/SavedVariables
3. Copy the GSE.lua file to your Desktop
4. Rename this copy to GSA.lua.txt
5. Then just drag it here in your message

• Note: If you do not include your GSE.lua file you are wasting your time and mine. 90% of the time, the first thing I will ask for is "Can you please upload your GSE.lua file?". This file is needed with the error to work out Why that error occured for you.

You have a corrupt 6th tab - which macro is it?

It was ELFYWW but I have scraped the whole macro and it's all working fine now. You can close it if you like. Thanks for the quick reply :)
