How to check empty with a number

Hello,

We can check if a number is empty in two ways. 😊

Note: Before proceeding to the solution, it's important to understand that "number empty" means the number has a value of 0.

1. Set the target value to 0 and test your logic. For example, if your variable is `$b-TableIndex1$`, assign `$tb-test$ = 0` and apply your logic accordingly.

2. If you specifically want to check for NULL, use a string condition instead of a number condition. Set the source value as your number variable (`$b-TableIndex1$`) and convert it into a string (type casting).

In source. -> `$b-TableIndex1.tostring$`

This approach should work for you. If you find this helpful, please consider marking it as the best answer. Happy automating! 🤖
