if i decrypt 2 fields with the same value, one returns correctly while the other returns funny character. Why?

Question

I'm using Cold Fusion for my webpage. The Encryption/Decryption program is written in VB6 where I call this program by using COM component in the Cold Fusion. Basically Cold Fusion is for frontend process and I use VB6 for my backend process. The VB6 backend process returns correct decrypted values. However if I call the program in Cold Fusion, some values return junk.
For example : 2 separate fields stores the same encrypted value. However upon decryption, one returns correctly while the other doesn't. If Basic Salary, Gross Salary and Net Salary contains the encrypted value of 0. Upon decryption, only the 1st field returns 0 and the rest returns blank or funny characters.

Thanks for the reply. FYI I'm using different variables for each field. Anyway, I've tried initializing the variables before every decryption. It still didnt work.

Answer 1

I think it is happening for over writing of variable. Clear the value of variable after decryption of one field & then perform another.
