function Msg takes string s returns nothing
    call DisplayTextToForce( GetPlayersAll(), s )
endfunction

function AddSubstract takes integer a, integer b returns nothing
   set udg_r1=a+b
   set udg_r2=a-b
endfunction

function Trig_JASS_test_Actions takes nothing returns nothing
 local integer a=14
 local integer b=56
    call AddSubstract takes(a,b)
    call Msg("a= "+I2S(a))
    call Msg("b= "+I2S(b))
    call Msg("The Addition is "+I2S(udg_r1))
    call Msg("The Substraction is "+I2S(udg_r2))

[B]    call AddSubstract takes(a,b)[/B]
    call Msg("a= "+I2S(a))
    call Msg("b= "+I2S(b))
    call Msg("The Addition is "+I2S(udg_r1))
    call Msg("The Substraction is "+I2S(udg_r2))
endfunction

Change to "call AddSubtract(a,b)". Simple error, but hard to notice sometimes, watch out
