You need xargs:
find . -name \*.txt | xargs grep -c "string"

grep -c is count lines, grep -l is list files. See man grep.

your original cmd works fine here:
grep -c "string" *.txt

did test in this way:
echo "one">1.txt
touch {2..1000}.txt

This will do it:
for mFName in *.txt; do
  mRC=$(grep -c 'string' ${mFName})
  if [[ "${mRC}" != "0" ]]; then
    echo "Found string in <${mFName}>"
