Any idea why this is wrong in Lua?
if Pieza == 1 then
if Rotacion == 1 then
Piezas = Cuadrado1
else if Rotacion == 2 then
Piezas = Cuadrado2
else if Rotacion == 3 then --this is Line 273
Piezas = Cuadrado3
else if Rotacion == 4 then
Piezas = Cuadrado4
else
io.write("Me Envio una rotacion que no existe? \n");
end
--this end closes the if inside the first if the one using to compare Rotacion
else if Pieza == 2 then
if Rotacion == 1 then
Piezas = I1
else if Rotacion == 2 then
Piezas = I2
else if Rotacion == 3 then
Piezas = I3
else if Rotacion == 4 then
Piezas = I4
else
io.write("Me Envio una rotacion que no existe? \n");
end
--this end closes the if inside the first if the one using to compare Rotacion
else --this else is in case Pieza != 1 || 2
io.write("Me Envio una pieza que no existe? \n");
end --this close the whole if (the one comparing "Pieza")
The error I'm getting is this 'end' expected (to close 'if' at line 273) near 'else'
Also, adding end after each if (this is not what should be done but tried it anyway) is not working...
If you need me to translate to english I will gladly do it commentaries and everything but I thought it wasn't neccesary for this question.

Lua, like most lanuages of this kind, has a "break" command that jumps out of the smallest enclosing loop. Normally you use "break" with "if" to decide when to exit the loop.
The usage of else if statement is optional is Lua programming language. The if.. else if.. else statement ends with the keyword end in Lua programming language. There can be any number of else if statements in a single if statement ending with else and end keyword.
1 – if then else. An if statement tests its condition and executes its then-part or its else-part accordingly. The else-part is optional.
It is always legal in Lua programming to nest if-else statements, which means you can use one if or else if statement inside another if or else if statement(s).
It's elseif, not else if (notice the space). The error is because the interpreter expects an end to each else block.
See the manual for more information.
