In my velleman mk109 kit

I assembled it after many attempts , now I have a problem could you all figure this out every press of the button results in a two, four , or seven what has happen to my other numbers ?

Most likely an assembly error.

If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.

I’ve just put this working video together for you’ll to view I guess I might have to reassemble it but put the resistors in first . see if you can spot the difference .its on a bread board .

Just rebuild the kit and follow the order stated in the manual. Breadboards are always dangerous because of their stray capacitance and bad contacts.
