'=' expected error

hi I keep getting a '=' expected error at line 5 of my 8 digit number generator code

code:

for i = 1, 8 do
  local ranChar = math.random(1,8)
  pass = pass ranChar
end
print("password is ",pass)

I sat at my computer for hours and could find it.
I need help with this problem

You need to concatenate ranchar with pass using ..

The code should look like this:

pass = ""
for i = 1, 8 do
  local ranChar = math.random(1,8)
  pass = pass..ranChar
end
print("password is ",pass)
