Legacy GM [Solved] Variable Index [10,0] out of range [10,-1]

[A Random Creator]

Hey everyone, I feel that I'm pretty experienced with arrays so when I seen this error I thought it would be a simple fix but I can't find the issue!
Here is my error:

Push :: Execution Error - Variable Index [10,0] out of range [10,-1] - -5._InventoryCraftS(100151,320000)
 at gml_Script_InventoryCraft (line 7) - if(_InventoryCraftS[t,v] = ds_map_find_value(_InventoryCraftList,v)) { } else { tBroke = 1 }

Here is the script where the error occurs:

///InventoryCraft()
tGotItem = 0 t=1 tBroke = 0

for(t=0;t<=array_height_2d(_InventoryCraftS);t+=1) {

for(v=0;v<=9;v+=1) {
if(_InventoryCraftS[t,v] = ds_map_find_value(_InventoryCraftList,v)) { } else { tBroke = 1 }
}

if(tBroke = 0) {
InventoryGiveItem(t,1)
for(z=1;z<=9;z+=1) {
ds_map_replace(_InventoryCraftList,z,0)
}
tGotItem = 1
}
}

if(tGotItem = 0) {
for(m=1;m<=9;m+=1) {
if(ds_map_find_value(_InventoryCraftList,m) != 0) { InventoryGiveItem(9,1) }
ds_map_replace(_InventoryCraftList,m,0)
}
}

So what this script is suppose to do is go through the array "_InventoryCraftS" and check if the map "_InventoryCraftList" values equal it. It is used to create a crafting menu sorta like Minecraft. It's kind of hard to explain so if you want more information then just ask. _InventoryCraftS is declared in this script:

///InventorySetCraft(Item ID, Slot: 1,2,3,4,5,6,7,8,9)
tID = argument0

_InventoryCraftS[tID,1] = argument1
_InventoryCraftS[tID,2] = argument2
_InventoryCraftS[tID,3] = argument3
_InventoryCraftS[tID,4] = argument4
_InventoryCraftS[tID,5] = argument5
_InventoryCraftS[tID,6] = argument6
_InventoryCraftS[tID,7] = argument7
_InventoryCraftS[tID,8] = argument8
_InventoryCraftS[tID,9] = argument9

_InventoryCraftList is a map that has 9 slots each one that will contain 0-9, so will _InventoryCraftS. I really don't know how else to explain it. If you need more info then please tell me. thanks!

I always try to fix bugs like this with the debugger. Try to look at the value of your variables and make sure its not going past the array size

The last index of an array is 1 less than its length, or in this instance, 1 less than the height.

Change the <= in your for loop to just <

thanks this fixed the issue!

arrays also start at index 0, not 1. if your array is size 10 then entry 0 through 9 are valid
