Hello Harun,

You can simply use parameters. To do it follow these steps:

1. Create two parameters.
2. Set their data sources to the same data sources as the tables.
3. Keep them invisible.
4. Set their value to the expression from the tables.
5. In the item you need perform the operation required using the two parameters.
