I am trying to parameterize one value,i have defined the parameter name,its type as "File",the file Path and kept it as sequential,but still its not substituting the values sequentialy with each iteration.its just taking the first value from the file.Can anyone suggest me the solution.
Try Update Value on Each Iteration Option...
You are using a txt or .dat file at the end of the path correct? Make sure that the parameter shows up in your parameter list and like nsc said, the parameter is changing on iteration.
Also, verify that the original values is not being passed elsewhere in the script. Check all web_submit function values for that parameter and make sure that the parameter you specified is represented for that value.
