problems about setting multi-parm in HDA processor

Hey guys, i have been developing my HDA tool for weeks and finally its done. the tool helps me generate a set of wall modules that could be used in my procedural building generation tool.
in my HDA tool, i need to assign a integer value(Let's say 'N') that represent the total number of sidewalls(which is a multi-parm), then the tool would generate N setting tabs for each sidewall. and in each tab i could further customize the details of each sidewall.
now, in order to batch generate many sets of modules, i was considering putting my HDA in PDG to automate the process.
During the process, there are two problems that i need to solve.
1. in my HDA tool ,there are constriants between some HDA parms that i implemented using callback scripts. however, in TOPS network, since the parms were assigned in parallel. the callback scripts constriant wont work properly. My current solution is to pre-generate all params in a python scripts.
2. now comes to the second issue, since i was using multi-parms in my HDA, the children tabs wont appear until the number('N') generated and assigned to it. so i have no idea where to put my variables.
any suggestions would be appreciated!

SWestthanks, i knew using parm as variables, but the main point it i dont have place to insert them since they were not generated before the multi-parm has been assigned a proper value.where to put my variables.
Just a quick suggestion could be to use the parm itself as a variable. Then build your code around that so it works. Use try and except to avoid errors.

You can first define a list that has zero length.
Later you can get the length of a (future) list from a multiparm.
Then you read each item from the multiparm into your list using a loop.
To get the name of the parm you first make a string for the parm name, then use that string to get a parm value.
I hope that helps.
Cheers!
