concatenation with nested functions

[Patrick <spell_gooder_now@...>]

Hi Everyone

The level of expertise is very high on this list and I am well below the 
median but if someone could lend this dummy a hand that would be great.

I am trying make a piece of code like this work.

function one() print[[long long string]]  .. function two() 
print('blah') end two() .. [[more of the long string]] end

I can't seem to figure out the correct parenthesis to allow the nested 
function to be concatenated between the two long strings.

Thanks for reading-Patrick
