Legacy GM [SOLVED] Draw tiled background on a portion of the screen

[A Random Creator]

Hello everyone, Im trying to make a room that has a black background with a tiled wood background on a portion of the screen. This might be way simpler than Im making it, but Im clueless.
here is my code:
Create:

MaxX = (room_width*0.8)/background_get_width(bgWood)
MaxY = (room_height*0.8)/background_get_height(bgWood)
MinX = room_width*0.1
MinY = room_height*0.1

Draw:

total = ((MaxX-MinX)/background_get_width(bgWood))+((MaxY-MinY)/background_get_height(bgWood))
tX = MinX tY = MinY

for(i=1;i<total;i+=1) {
draw_background(bgWood,tX,tY)
tX += background_get_width(bgWood)
if(tX >= MaxX) { tx = MinX tY += background_get_height(bgWood) }
}

if you know what is wrong or you know a better way to do this then please tell me! Thanks!
P.S. I was kinda in a rush when I made this post, so if you need more information or something then please message me =)

MaxX = (room_width*0.8)/background_get_width(bgWood) <==Remove the division
MaxY = (room_height*0.8)/background_get_height(bgWood) <==Remove the division
MinX = room_width*0.1
MinY = room_height*0.1

MinY = room_height*0.1

Yeah, that was a big problem, but I fixed that and now it is showing the background but it doesn't cover the whole area it should. Once it hits the MaxX it doesn't stop. it makes a line like this:

OH! You have a typo! You used tx=MinX instead of tX=MinX.
