Hi,
I am trying to show a caculate result in a specific format in the group footer row. If I only format a single aggregate value, it works fine but a double parameter does not work. I get the error message "An error has occured while processing TextBox 'textBox5':
The expression contains undefined function call GetTimeString2()"
So basically if I do this
=GetTimeString1(Sum(Fields.Hours))
or I do this
=GetTimeString1(Sum(Fields.Minutes))
it works fine, but if I do this
=GetTimeString2(Sum(Fields.Hours), Sum(Fields.Minutes))
it does NOT work and I get the above error message and even if I try this
=GetTimeString2(Sum(Fields.Hours), 40)
it does NOT work, but this will work
=GetTimeString2(2, 40)
So basically if there is an aggregate, one or many doesn't matter, it will not work.
the static function signature are
=========================
public static string GetTimeString1(int hrs)
public static string GetTimeString2(int hrs, int mins)
Can someone point out why it won't take two aggregates in the function. I looked at the limitations post and it does not look like this is a limitation.
Thanks for your assistance.

Hi Enigma,
Internally all of the data types are converted to the "biggest" numeric data types (long and double) to avoid any data/precision loss (common practice in scripting languages). In this line of thoughts the Sum aggregate returns Int64 (long) data type when we sum int values. In order the expression engine to recognize your User Function you have to modify it to accept Int64 parameters as shown in the following code snippet:
