Enabling/disabling dynamically generated control via another dynamically generated control

I have a userform that creates a new multipage with each press of a button.

Some of these dynamic controls must be Enabled/disabled via the selection or input values from other dynamically created controls.

do not seem to work of have any effect on the controls I want to enable/disable.

I suspect this issue may be solved by the use of a Class but I frankly need help in understanding classes and their use in vba.

Any help on this would be appreciated.
