Thread: while loop not resetting

hello everyone,
I've tried to construct a nested while loop and for the nested loop the value output isn't returning to 0 at the beginning of the new loop. How might I fix this. Also, the final return value of successful vs unsuccessful simulations is wrong but also inconsistent. I would appreciate any help offered to solve either problem.

Code:

int main(){
    int flag = 1;
    int days, failure,run=0, success, adjustments, simulations, trial=0;
    printf("How many days did we use the simulator?\n");
        scanf("%d", &days);
        while (flag){
            (trial++);
             printf("How many simulations did we run on day %d?\n", trial);
                scanf("%d", &simulations);
            int tag=1;
                while (tag){
                    (run++);
                    printf("How many adjustments were needed for run #%d?\n", run);
                        scanf("%d", &adjustments);
                if (run == simulations)
                    tag =0;}
                    if (adjustments >= 5)
                        failure=run;
                        printf("Day #%d: There were %d successful simulations.\n", trial, success);
                        printf("\n");
                if (trial == days)
                    flag = 0;}
