SCL Problems, calling an FB

HELLO!
I've created a FB that's supposed to return a value through an output variable.
here's the FB code:

FUNCTION_BLOCK FB_Scalare
VAR_INPUT
valcitita:INT;
minR:INT;
maxR:INT;
minM:INT;
maxM:INT;
offset:INT;
END_VAR
VAR_OUTPUT
p1:REAL;
BEGIN
p1:=(maxM-minM)/(maxR-minR)*valcitita+offset;
END_FUNCTION_BLOCK

this is the OB:

ORGANIZATION_BLOCK CICLU_TK1
(*******************************************************************************
CYCLE corresponds to OB1; that is, it is called cyclically by the S7 system
Part 1 : Calls function block and transfers input data
Part 2 : Copies output data and outputs data with switch to output
********************************************************************************)
VAR_TEMP
systemdata : ARRAY[0..20] OF BYTE; // Range for OB1
//tempo_ana:WORD;
END_VAR

BEGIN
TON.DB1(IN :=TK1_DI_M02_1,PT :=T#2S);
TONMOTOR1:=DB1.Q;

TON.DB2(IN :=TK1_DI_M02_1,PT :=T#2.5S);
TONMOTOR2:=DB2.Q;

TK1_DOR_M07_1:=NOT TK1_DI_M02_1;

//CONTOR PORNIRI MOTOR
IF TK1_DI_M02_1 AND NOT TK1_DI_M02_1 THEN
MOT1_BIT_CONTROL:=TRUE;
END_IF;

IF MOT1_BIT_CONTROL=TRUE AND DB1.Q=TRUE THEN
MOT1_CONTOR:= MOT1_CONTOR+1;
MOT1_BIT_CONTROL:=FALSE;
END_IF;

tempo1:=(tempo_citit1);
tempo3:=(tempo_citit3);
tempo5:=(tempo_citit5);
tempo7:=(tempo_citit7);
//MS_IN_COND_TG:=PIW548;

FC_CONTOR.TEST();
FB_Scalare.Scalare (15,0,16,202,27400,202);
p1:=Scalare.p1;
END_ORGANIZATION_BLOCK


when i compile the OB the debuger tell's me i have an error "Right paranthesis missing", and it point's the cursor between the right paranthesis and ";".
PS. FB_Scalare it's the symbol for the FB and Scalare it's the symmbol for the DB used for FB.
Any clues about this?
thx in advance.

This will not compile as there are loads of variables in OB1 that are not declared (tempo1 etc) - please post the code as you would expect someone else to compile it and get the same error you are getting.

my problem is not tempo1 and those variables, because those variables are declared in the symbol table. the problem i'm getting is when i call the function.

i'm posting here the whole project so that you can compile it and get the same errors as i do.

When you call a function block you must specify the parameter names, not just a list of values. See example below.

thank you for your reply. it sure helped me.
as i said before this is my first project with siemens, and i'm just 18 years old, and i'm helping my father to do this project because he can't do it all by himself.
