I use Crystal 11 R2 SP3 and Sybase 15

I want to use stored procedure for my report.

This procedure have one input parameter of datatype int.

When I choose this procedure as dataset,a window displays, where I

 am ordered to enter input parameter.

For example,I input 2.

Crystal dispays error :

"22018 Implicit conversion from datatype varchar to int is not allowed.
Use the CONVERT function to run this query "

I input convert(int,'2').

There is same error.

 

Thanks..
