Empty Result Variable

[Guest KB]

One of my "get numbers" modules can return an empty value, meaning the user don't have to dial in a number and it will move on after two seconds, following is a VB script which checks this value, how can i check whether the value was empty? is it equal to an empty string or false?

 

Thanks.

An undefined RV is equal to an empty string.

 

To test if the RV is defines use an expression like this in an Evaluate Expression module:

 

"$RV[someModule]"=""
