error

the result of prechecking the pre.err file tells where the mistake is, but usually the mistake is not where it tells. my problem is that i need to set slope of each branch so i set them different waterbodies, 13 waterbodies in all, but the control file can't pass the prechecking. the file pre.err told there are mistakes in the output control card as follows WB 9 WB 10 WB 11 WB 12 WB 13 the all SNP related cards in the control file as following SNP PRINT SNPC NSNP NISNP WB 1 OFF WB 2 OFF WB 3 OFF WB 4 OFF WB 5 OFF WB 6 OFF WB 7 OFF WB 8 OFF WB 9 OFF WB 10 OFF WB 11 OFF WB 12 OFF WB 13 OFF SNP DATE SNPD SNPD SNPD SNPD SNPD SNPD SNPD SNPD SNPD WB 1 WB 2 WB 3 WB 4 WB 5 WB 6 WB 7 WB 8 WB 9 WB 10 WB 11 WB 12 WB 13 SNP FREQ SNPF SNPF SNPF SNPF SNPF SNPF SNPF SNPF SNPF WB 1 WB 2 WB 3 WB 4 WB 5 WB 6 WB 7 WB 8 WB 9 WB 10 WB 11 WB 12 WB 13 SNP SEG ISNP ISNP ISNP ISNP ISNP ISNP ISNP ISNP ISNP WB 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 27 28 29 30 31 WB 2 WB 3 WB 4 WB 5 WB 6 WB 7 WB 8 WB 9 WB 10 WB 11 WB 12 WB 13 as i see it this card is so simple that it can't be wrong, and i have removed the unnecessary spaces. where the problem can be? how should i correct it?
