Need help finding a block in a radius at a specific Y coordinate, and teleporting the player to it in mcreator 2024.4

I have a procedure that I thought would work, and had help from friends who are better at java stuff than I, but it doesn't seem to be saving the coordinates in the variables I gave it whether they be global or not. It prints that it found air but never actually works, there were many iterations of this code before I caved and made an account here to ask how I should fix it. 

Sorry if it looks like a mess, again I tried several times for this code to work, and it doesn't have a global procedure as it's called externally. 
Thanks in advance if you decide to help.
