Stuck with search funktion

Hi
Im trying to create 2 diffrent search funktion and im stuck.
The first one is made to look into a datasheet and match 2 diffrent values from a userform and see if theres a match. If it finds a match a new userform pops up and ask if you want to replace the old values in the datasheet. But that means it have to get a fix on the adress from the match on the first userform, i tryed to solve it by creating 2 diffrent seraches, but i cant get them to work.

Hope somebody can help me!
