Hello,

i want to get a random number between 0 and 149. i used Math.random() function. i tried to convert to int which i get from this function but i couldnt get it as integer, i get it as double. i am going to use this variable in dataset-get action row property. Can you help me? Thanks.

This is the script:

```auto
var randomSayi = execution.getVariable("randomSayi");

randomSayi = parseInt(randomSayi);
execution.setVariable("randomSayi", randomSayi);
