HElp with AEL coding in Agilent ADS for Bandpass filter

We have already segmented a Bandpass filter, into different parts and we plan to cascade it in future.

Our main goal is to use AEL to run our schematic multiple times in loops (We HAVE to SAVE the results each time), for different parameters of (Length, Width and the Gap between TL lines).

Can some one help me with writing a loop in AEL which will enable me to run my simulation multiple times for varying, Length, Width and the Gap between TL lines.

You can still do it with sweep parameter to capture results for different parameters
