If you configure your variable change policy to "on each use" a new value will be used each time. Have you tried this?
Hi,
I try to put a variable change policy but it doesn't work. I put the name of the variable but when I put the name of the column name, it show the variable on the validation but report an error Vm-var-not-found
You misunderstood, not the variable modifier. If you open the variable manager dialog, select the variable you want, on the right hand side at the bottom of the dialog, you will see the change policy, on each use, on each request, on each page and so on. Select the on each use.
Hi Neil,
I have change the parameter of my variable, but it doesn't change.
it should, every time you loop around it should be getting the next row (ID)
