Problem with submitting dependent job in slurm - bash

Question

I'm using the following .sh script to submit some Slurm jobs.
# Set hardware resource requests
nb_partitions=200 # number of distinct partitions to which you'll send sbatch statements
nb_threads=7 # number of CPUs requested per partition
# Make directory in which you'll store results
mkdir results
# Make a separate folder for each partition
for j in $(seq 1 $nb_partitions)
do
mkdir results/partition$j
done
# Copy MainFolder which has code for execution to each partition folder and change partition number stored in each input file to correspond to its number
for i in $(seq 1 $nb_partitions)
do
cp -r MainFolder results/partition$i
sed -i "1s/.*/${i[#]}/g" results/partition$i/MainFolder/partition_nb.txt
done
echo "Files and folders have been copied and created."
# Loop to submit simulations job for each partition
slurmids="" # storage of slurm job ids
for k in $(seq 1 $nb_partitions)
do
cd results/partition$k/MainFolder
# Write parameters to files within the main folder so they can be read into FORTRAN
echo "$nb_partitions" >> nb_partitions.txt
echo "$nb_threads" >> nb_threads.txt
slurmids="$slurmids:$(sbatch --parsable --cpus-per-task=$nb_threads run.sh)"
cd ..
cd ..
cd ..
done
echo "Jobs are now running."
# Submit job to combine files
ID=$(sbatch --dependency=afterok=$slurmids combine_results.sh)
The final line of this code is supposed to submit a batch job that will execute only after all of the other jobs submitted in the loop are done. However, when I run this shell script the job combine_results in the final line of code never runs. The Slurm manager simply says the job is waiting because the dependencies are not satisifed.
Any ideas on what I'm doing wrong here? Thanks!
