Alright, let's figure out why your currentLocation() function is throwing that unexpected symbol near '=' error—this is a classic syntax issue, easy to fix once we break it down.

First, let's walk through the problems in your original code:

• You forgot to start the function with the function keyword. Lua requires this to define a function properly, so without it, the interpreter has no idea what you're trying to declare.
• The line currentX, currentY = GetMouseremove_style_tag> is completely broken. That GetMouseremove_style_tag looks like a typo or leftover markup, and the stray > is the immediate cause of the syntax error. Lua sees that > and can't parse the currentY = ... assignment that follows right after. I’m guessing you meant to call a valid mouse coordinate function here, like GetMousePosition() (or whatever your environment uses to get raw mouse positions).
• Also, if height and width aren’t defined elsewhere in your code, you’ll hit another error once you fix the syntax—so make sure those variables are set to your screen/canvas dimensions before running this function.

Here's the fixed version of your function, with clear explanations for each change:

function currentLocation()
    -- Replace GetMousePosition() with the actual mouse coordinate function from your environment
    local currentX, currentY = GetMousePosition()
    
    -- Convert raw 0-65535 coordinates to your target dimensions
    currentY = height * currentY / 65535
    currentX = width * currentX / 65535
    
    -- Round down to whole integer values
    currentX = math.floor(currentX)
    currentY = math.floor(currentY)
    
    return currentX, currentY
end

Key fixes I made:

1. Added the function keyword to properly declare currentLocation().
2. Fixed the mouse coordinate line—replaced the broken markup/typo with a valid function call. I also added local to currentX and currentY to keep them scoped to the function, which is best practice in Lua to avoid messy global variable clutter.
3. Added line breaks to make the code readable (Lua allows one-liners, but this is way easier to debug and maintain).
4. Kept your core coordinate conversion and flooring logic intact—it looks correct, assuming your raw mouse coordinates are in a 0-65535 range (common in some APIs).

One extra tip: If height and width should vary depending on where you call the function, you can turn them into parameters instead of relying on global variables. Here's how that would look:

function currentLocation(targetWidth, targetHeight)
    local currentX, currentY = GetMousePosition()
    currentY = targetHeight * currentY / 65535
    currentX = targetWidth * currentX / 65535
    currentX = math.floor(currentX)
    currentY = math.floor(currentY)
    return currentX, currentY
end

Just make sure to replace GetMousePosition() with the actual function name your setup uses to retrieve mouse coordinates, and you should be good to go!
