tblMark RECORD;
parCount INTEGER;
parNonCount INTEGER;
totalParNonCount TEXT;
tblCou INTEGER;
BEGIN
parCount=0;
parNonCount=0;
FOR tblMark IN (SELECT * FROM "LandXML_QCC_ParcelMarks" WHERE "DPID" = PlanID) LOOP
SELECT COUNT(*) INTO tblCou FROM "LandXML_QCC_ParcelInformation"
WHERE "DPID"=PlanID
AND (
"Pntref" LIKE '%' || tblMark.From || ',' || tblMark.Name '%'
OR
"Pntref" LIKE '%' || tblMark.Name || ',' || tblMark.From '%'
);
RAISE NOTICE 'Value: %', tblCou;
IF tblCou > 0 THEN

Answer 1

In your SELECT inside the FOR loop, you have the following condition:
... AND (
"Pntref" LIKE '%' || tblMark.From || ',' || tblMark.Name '%'
OR
"Pntref" LIKE '%' || tblMark.Name || ',' || tblMark.From '%'
)
You are missing the concatenation-operator || for the trailing '%' both times. Also, you are not properly referencing the columns of your record. Since you established them with " (double-quotes), you will always need to refer to them exactly the same way (This is a reason why you should not do this. So if it is not to late, change it to names without quotes.).
Using your momentary columnnames, this should help you:
... AND (
"Pntref" LIKE '%' || tblMark."From" || ',' || tblMark."Name" || '%'
OR
"Pntref" LIKE '%' || tblMark."Name" || ',' || tblMark."From" || '%'
)
