Crystal Reports Formula to generate a random number - crystal-reports

Question

Let assume
x = 1001
Now I am inputting x to my code and generating y in the following order:
Length of 1001 is 4 so starting from the last number
i.e. 1(number) * 4(position of number) & 0 * 3 & 0 * 2 & 1 * 1 that gives a new number 4001
Another eg. 1234 gives 16941
In crystal I am creating a formual as follows:
stringvar tmp_EventNo;
stringvar tmp_Password;
numbervar i;
numbervar m_password;
tmp_EventNo = Trim(ToText({GR_EVENT.event_number}));
For i := Len(tmp_EventNo) To 1 Step -1 Do
(
tmp_PassWord = tmp_PassWord & Trim(ToText(Val(Mid(tmp_EventNo, i, 1)) + i));
);
m_Password = Val(tmp_PassWord);
m_password
But it doesnt seem to work. Just results in 0.00
Please help thanks in advance

Nice easy one- you will kick yourself :)
In Crystal = is used for evaluation. := is used for assignment.]
There were a few other issues with the code so i tweaked it for you:
stringvar tmp_EventNo;
stringvar tmp_Password;
numbervar i;
numbervar m_password;
tmp_EventNo := Trim(ToText({GR_EVENT.event_number}, 0, ''));
For i := Len(tmp_EventNo) To 1 Step -1 Do
(
tmp_PassWord := tmp_PassWord & Trim(ToText(Val(Mid(tmp_EventNo, i, 1)) * i,0));
);
m_Password := Val(tmp_PassWord);
tmp_PassWord;
