How to give input in popups after running macro

I have to run one macro after running that macro it will ask input, i have to give the input like first row number and last row number after giving that input it will process that set of rows and again it will ask input for first row and last row for another brand, like it will ask for three, here my doubt is how to give that inputs after execute macro activity, i tried with parallel activity, but after giving first input it will take some time to process that rows after that it will ask second input, there i am getting error while using parallel activity. can anyone help me in this.


Do you think On Element Appear (macro input pop up) will work in this case?
