unexpected token `fi' in script - bash

Question

Whenever I run the bash script I encounter this problem:
LRU.sh: line 121: syntax error near unexpected token `fi'
The script is:
#!/bin/bash
declare -i numOfPageRRef=0
declare -i numOfFrames=$1
declare -i a=0
declare -i k=0
declare -i c=0
declare -i q
declare -i c1=0
OIFS=$IFS
IFS=','
read line < Input2.csv
for val in $line
do
pageRef[$numOfPageRRef]=$val
((numOfPageRRef++))
done
#echo ${pageRef[#]}
q[$k]=${pageRef[$k]} #chck here
echo ${q[$k]}
((c++))
((k++))
for((i=1;i<numOfPageRRef;i++))
do
c1=0
for((j=0;j<numOfFrames;j++))
do
if (( ${pageRef[$i]} -ne ${q[$j]} ))
then
((c1++))
fi
done
if (( c1 -eq numOfFrames ))
then
((c++))
if (( k -lt numOfFrames )) ;then
q[$k]=${pageRef[$i]}
((k++))
for((j=0;j<numOfFrames;j++))
do
echo ${q[$j]}
done
else
for((r=0;r<numOfFrames;r++))
do
c2[r]=0
for((j=i-1;j<numOfPageRRef;j--))
do
if (( ${q[$r]} -ne ${p[$j]} ))
then
((c2[r]++))
else break

done
done
for((r=0;r<numOfFrames;r++))
do
t4=${c2[r]}
b[$r]=$t4

do
for((j=r;j<numOfFrames;j++))
do

Answer 1

Your error is because you missed a done closing statement, when i remade all the syntax in your code i was able to see it, its in the bottom. so here is your code without the error.
P.S
In the future please pay attention on the syntax, it makes big difference while reading the code.
OIFS=$IFS
IFS=','
read line < Input2.csv
for val in $line
do
pageRef[$numOfPageRRef]=$val
((numOfPageRRef++))
done
#echo ${pageRef[#]}
q[$k]=${pageRef[$k]} #check here
echo ${q[$k]}
((c++))
((k++))
for((i=1;i<numOfPageRRef;i++))
do
c1=0
for((j=0;j<numOfFrames;j++))
do
if (( ${pageRef[$i]} -ne ${q[$j]} ))
then
((c1++))
fi
done
if (( c1 -eq numOfFrames ))
then
((c++))
if (( k -lt numOfFrames ))
then
q[$k]=${pageRef[$i]}
((k++))
for((j=0;j<numOfFrames;j++))
do
echo ${q[$j]}
done
else
for((r=0;r<numOfFrames;r++))
do
c2[r]=0
for((j=i-1;j<numOfPageRRef;j--))
do
if (( ${q[$r]} -ne ${p[$j]} ))
then
((c2[r]++))
else break
fi
done
done
for((r=0;r<numOfFrames;r++))
do
t4=${c2[r]}
b[$r]=$t4
for((r=0;r<numOfFrames;r++))
do
for((j=r;j<numOfFrames;j++))
do
if (( ${b[$r]} -ne ${b[$j]} ))
then
t=${b[r]}

b[$r]=$t2
