Hi everybody,

I want to do a random sampling by setting a macro & looping on different values , but it seems that when I loop through the values , only the first value is applied ,

Actually as the result of the following code I want to have a multiple files each containing the result of the X-validation , but it only applies the first value,

Thanks ,

    The error is in the "Set Macro" operator. The parameter "macro" has to be set without the "%{" and "}" but only "r". What happens behind the curtain is that the first iteration sets the value for the macro "r" correctly (the % and the curly brackets will be ignored here, because no macro with the name "r" is known), but in the second iterations the macro in the parameter "macro" will be replaced by the value of the macro "r" from first iteration. So in the end you will set "r" to the first value in the "Loop Parameters" operator and the last value to a macro with the name of your first value.

    To put it in a nutshell, replace "%{r}" with "r" in the "Set Macro" operator.
