Dynamic Masking using Checkboxes

Hello,
I'm having some trouble getting a dynamic mask setup that uses checkboxes. I'm trying to create a block where checkboxes control which output ports are visible and not. I'd like it so that when a checkbox is unchecked, it's corresponding block output port is no longer visible. Here is the code I've found and modified for the dialog callback:
thisVariable = 'quatStatus';
affectedVars = 'Port';
thisBlock = gcb();
thisVarState = get_param(thisBlock, thisVariable);
maskNames = get_param(thisBlock, 'MaskNames');
maskEnables = get_param(thisBlock, 'MaskEnables');
for varName = affectedVars
varIndex = find(ismember(maskNames, varName));
maskEnables{varIndex} = thisVarState;
end
set_param(thisBlock, 'MaskEnables', maskEnables);
where quatStatus is the variable I've assigned to the checkbox parameter. I think the issue is that I'm not controlling the port I'm interested in.
Thanks!

Thanks for the info. I gave it a look through and found this bit that looks helpful:
enab = get_param(gcb,'quatStatus');
if strcmp(enab,'on')
set_param(gcb, ???, 'on');
else
set_param(gcb, ???, 'off');
end
However, I'm still having trouble setting the port mask visibilities. I'm not sure how to select the port of interest and control its visibility. Is this done in the with the set_param function?
Thanks!

Is this process done with something simple like a set_param call that hides that portion of the mask? Or do I need to actually have it create/delete ports?
