I have this if statement and when I run it it reeturns an error : " ')' expected "

if (a=1 and b=4 and c=width/2) or (a=2 and b=1 and c=width/2) then
...
end

Am I doing something wrong here? or is it something wrong with lua?

I think your = need to be ==. = sets a value while == compares values. — showdev

Not that I know much about Lua.. But should it not be == and not =? — MAV

Try to replace your current code with this:

if (a==1 and b==4 and c==width/2) or (a==2 and b==1 and c==width/2) then
...
end

= means assignment, whereas == checks for equality and it looks like you want to check for equality.
