If statement in while Loop

[DroskiDro]

The code runs without an error, but the outfile shows that it isn't properly incrementing the values for temp_fail, press_fail, and dwell_fail, I can't seem to figure out why.

#include<stdlib.h>
#include<stdio.h>
#include<conio.h>
#define FILENAME "suture.txt"

main()
{
      int numdata=0, temp_fail=0, press_fail=0, dwell_fail=0, batchnum=0;
      float temp, press, dwell;
      FILE *infile;
      FILE *outfile;
      outfile = fopen("Lynch_outfile.txt","w");
      infile = fopen(FILENAME, "r");
             if(infile == NULL)
                printf("Error opening input file.");        
             else
             {
                 while((fscanf(infile,"%lf %lf %lf %lf",&batchnum, &temp, &press, &dwell)==4))
                 {
                  if(temp<150 || temp>170)
                       temp_fail++;      
                  if(press<60 || press>70)
                       press_fail++;
                  if(dwell<2 || dwell>2.5)
                       dwell_fail++;
                  numdata++;        
                  }
                 fprintf(outfile,"Total defective batches:         %i\n", numdata);
                 fprintf(outfile,"Defective due to temperature:    %.3f (%.2f %)\n", temp_fail, (temp_fail/numdata)*100);
                 fprintf(outfile,"Defective due to pressure:       %.3f (%.2f %)\n", press_fail, (press_fail/numdata)*100);
                 fprintf(outfile,"Defective due to dwell time:     %.3f (%.2f %)\n", dwell_fail, (dwell_fail/numdata)*100);
                 fclose(infile);
                 fclose(outfile);
             }
      getch();
      return 0;
}

The infile "suture.txt" looks like

24551 145.5 62.3 2.13
24582 153.7 63.0 2.52
26553 160.4 58.8 2.51
26613 159.5 58.9 2.02
26624 160.5 61.5 1.98
27725 170.9 62.5 2.03

My current outfile "Lynch_outfile.txt" looks like

Total defective batches:         6
Defective due to temperature:    0.000 (0.00 )
Defective due to pressure:       0.000 (0.00 )
Defective due to dwell time:     0.000 (0.00 )

Now I just feel silly :(
Thank you, Dev-C++ doesn't show all that.
