Referencing to LIST doesn't work with + and - operations.

Hi Hasib,

Could you please provide additional information about the comparison you are making?

List columns/rows start from 0, not 1. So if you are grabbing a value from the web page where the XPath dynamically moves with your Loop starting with the number 1, your list will start with 0 and that should be taken into account, you can use separate variables for that if your XPath does find anything with 0 and always starts with 1.

Hi Jespeh,

Yes, I'm aware of it, the problem is calculations such as [@index-1] doesn't work when referencing to the list values.

For example, @index= 2 which is the the variable assigned by the loop counter. Since the list rows starts by 0 , I would use below expression to row 2:

@list_name[@index-1][1] 
@{list_name.column_name}[@index-1]

None of the above woks but if I use @list_name[@index][1] or @list_name[1][1] it works. My point is calculation inside the brackets are not working. 

Hi Hasib,

Thanks for clarifying. Compare command expects to be provided with 2 values and it can read through variable values, but it cannot perform arithmetic operations. The only command that can do that is Set_Var with Expression type. Since your Loop always starts with 1 and you want to start with 0 for the list, you can create a Set_Var step with value 0 that runs before your loop, then inside the loop before the next iteration, you can add another Set_Var step with Expression type that increases the value by 1 for the same variable, so it keeps it moving. For example, notice steps 2, 5 and 6 below:

Please let me know if this makes sense or if you have any other questions.

Thank you, I used set_var to do the calculation and used the new variable in the compare step. Do you think it's a good enhancement to make compare steps take care of calculation?

Hi Hasib,

Glad to hear it works. You are welcome to submit a feature request, but making Compare command perform calculations defeats the purpose of the command as it's built to compare between values (static or dynamic), but not perform calculations.
