Not a uniquely defined Name? - cobol

Question

I keep getting the error
"LOWMID-COMMISSION-CTR" was not a uniquely defined name. The definition
to be used could not be determined from the context.
And similar on all of my counters. I have no idea where I'm going wrong here, how is it not a uniquely defined name when it is clearly in the WORKING-STORAGE SECTION? Do I put it somewhere else so that it's a uniquely defined name? Below I have showed where I defined my counters, and where the counters are used.

Answer 1

Thje variable LOWMID-COMMISSION-CTR is defined twice.
once in FLAGS-AND-ACCUMLATORS
01 FLAGS-AND-ACCUMLATORS.
05 LOW-COMMISSION-CTR PIC 99999 VALUE ZERO.
05 LOWMID-COMMISSION-CTR PIC 99999 VALUE ZERO.
once in HEADING-LINE-4
01 HEADING-LINE-4.
05 PIC X(03) VALUE SPACES.
05 PIC X(52) VALUE
"Number of employees from 10,001 to 20,000 in sales: ".
05 LOWMID-COMMISSION-CTR PIC 99999.
So either
rename one of the LOWMID-COMMISSION-CTR to some thing else
01 HEADING-LINE-4.
05 PIC X(03) VALUE SPACES.
05 PIC X(52) VALUE
"Number of employees from 10,001 to 20,000 in sales: ".
05 HEADER-LOWMID-COMMISSION-CTR PIC 99999.
fully qualify the field.
Add 1
to LOWMID-COMMISSION-CTR
of FLAGS-AND-ACCUMLATORS
Same applies to other FLAGS-AND-ACCUMLATORS fields
