It seems to me you took my example and removed what you thought you didn't need.
Unfortunately you also took away a lot of things you do need if you want it to work like you said above.
The things you ask for now are relatively easy if you know how to make a program with Construct2.
Add another condition to the event adding the framenumber.
System compare to values - Total wanted - is equal or less than - total + framenumber
this way the event will not trigger when the count will be more than total wanted.
instead of restarting the layout when wanted total is reached just destroy the selected numbers and set total to 0 and wanted total to random.
To see which numbers were selected make a boolean variable on the sprite and trigger this to true if clicked on.
