Hey folks me again.
I've made some good progress on my project, right now I'm trying to index the stepper motor axis
This runs through a few steps.
1: If the stepper is on the switch, continue rotating until it is no longer on the switch
2. rotate until the switch is pressed another time
3. back off of the switch until it is no longer pressed
4. set the table is indexed.
I need to figure out how to interrupt it with if the "STOP" switch is pressed too at some point, Right now I was trying to track this by "do step 1 until the state is good to go, then set a variable to "i'm done" and step 2 picks up if the "i'm done" variable is set to its value
Now this sort of kind of works, it appears my IF statements aren't good enough and aren't capturing from the previous loop since it will jump to the bottom instead of to the next step (or so it appears).
I'm almost 100% sure this is a terrible way of going about this, I dont need the code rewritten just show me how I should be doing this kinda flow
Thanks folks!

int indexfunction() {
int indexresult = 0; //indexresult vars: --0=unindexed --1=indexed --2=first stage done --3=second stage done 4= third stage done

indexstate = digitalRead(indexswitch);
estopstate = digitalRead(estopbutton);
while (indexresult == 0) {

digitalWrite(indexmotor, HIGH);
