Count rows where a column of combined values contains a specific text

[JWPowder]

Hello, I have column of 3 letter defect codes in a QC data tracker table. These values are combined when they are entered into the PowerApp I use to records the data. 

I am now trying to create a pareto chart pf the top 3-letter defect codes in a given period. I am stuck on the measure to count if the column contains a specific defect code. 

There are over 20 different defect codes I will have to write measures to count. 

I have tried several of the DAX responses on previous posts with no avail. Examples below: 

APP Count = COUNTROWS (
    FILTER ( HILLIARDQCDATA, CONTAINSSTRING ( HILLIARDQCDATA[Defect Code(s)], "APP," ) )
)

Countif:=CALCULATE(
COUNTROWS(Table),
SEARCH("a",Table[names],,0))

Data: 

Table of Defect Codes:

Column I need to count is Defect Code(s):

Any help or tips are very much appreciated. 

Thank you in advance!

Hi @JWPowder ,

Based on your question, you can follow the measure below.

Sample data:

Add a new measure:

SDS COUNT = 
VAR _ture_or_false =
    CONTAINSSTRING ( SELECTEDVALUE ( 'Table (2)'[Defect Code(s)] ), "SDS" )
VAR _text_app =
    IF ( _ture_or_false = TRUE (), 1, 0 )
RETURN
    CALCULATE ( COUNTROWS ( 'Table (2)' ), FILTER ( 'Table (2)', _text_app = 1 ) )

RESULT = SUMX('Table (2)','Table (2)'[SDS COUNT])

Final output:
