awk syntax error calling user defined function

I get a syntax error:

/usr/xpg4/bin/awk: file "./test.awk": line 64: syntax error
Context is:
>>>   printf (", %s", date_value  ( $3, fmt_yyyymmdd ) );   <<<

The code fragments are:

fmt_yyyymmdd="yyyymmdd";
printf (", %s", date_value  ($22, fmt_yyyymmdd ) );

...

function date_value(string, format)
{
    return "20150101";
}

I am not able to understand where the syntax error is. A very similar statement (with one parameter only) produces no syntax error and works correctly.

printf (", %s", char_value  ( $2) );

For me it seems that awk either does not allow calling a user defined function with a parameter being a user defined variable or literal or calling a user defined function with more than one parameter. I am unfortunately not proficient in awk.

I think the problem is how you call the function. In user-defined functions it cannot exist any space between the name and the parameters, use:

printf (", %s", date_value($22, fmt_yyyymmdd ) );
