Syntax error: Bad for loop variable

I'm getting an error while running this script. Need help.

Code:
set -x verbose #echo on
clear #clear the screen

USERNAME="bbb"
PASSWORD="password"
SERVER="192.168.1.100"
WAIT_TIME=300
FILE_PATH="/home/users/xxx/MMM" # local directory to pickup *.dat file
REMOTE_PATH="/Drop_off/xxx/yyy" # remote server directory to upload file

#Process files
for file in $FILE_PATH/*.dat
do
	echo "Processing $file ..."
	# take action on each file. f store current file name
	./UFTFTP_SecondScript $file
	echo "Seconds until next uploadls : $WAIT_TIME"
	for (( x=0; x<$WAIT_TIME"; x++ ))
	do
		echo "Sleeping for " $x
		sleep 1
	done
done

-----------UFTFTP_SecondScript------------
Code:
#!/bin/sh

set -x verbose #echo on

#CURRENT PROCESSING FILE: 1
#USERNAME: 2
#PASSWORD: 3
#SERVER: 4
#FILE_PATH: 5
#REMOTE_PATH: 6

#login to remote server
ftp -n -i $4 
<<END_INPUT
	user $2 $3
	cd $6
	mput $5/$1 
	quit
END_INPUT

Hi.

Did you miss a quote, on this line:
Code:
for (( x=0; x<$WAIT_TIME"; x++ ))

# 3  
I removed the quote but i'm still having the same error.
# 4  
What's your system? What's your shell? Not all shells have for ((x=0; x<5; x++)) syntax

You could do

Code:
X=0
while [ "$X" -lt "$WAIT_TIME" ]
do
...
        X=`expr $X + 1`
done

I noticed that I wasn't passing all parameters but I'm still having the same issue.
Code:
USERNAME="bbb"
PASSWORD="password"
SERVER="192.168.1.100"
WAIT_TIME=300
FILE_PATH="/home/users/xxx/MMM" # local directory to pickup *.dat file
REMOTE_PATH="/Drop_off/xxx/yyy" # remote server directory to upload file

#Process files
for file in $FILE_PATH/*.dat
do
	echo "Processing $file ..."
	# take action on each file. f store current file name
	./UFTFTP_SecondScript $file $USERNAME $PASSWORD $SERVER $FILE_PATH $REMOTE_PATH
	echo "Seconds until next uploadls : $WAIT_TIME"
	for (( x=0; x<$WAIT_TIME; x++ ))
	do
		echo "Sleeping for " $x
		sleep 1
	done
done

You could try x<WAIT_TIME instead of $WAIT_TIME. Inside (( )) the $ shouldn't be necessary.

Or you could try my loop above

What is the value of WAIT_TIME? Make sure the value contains no spaces, etc. which might interfere with comparison
# 7  
WAIT_TIME=300

I tried with your loop and it worked.

Code:
#Process files
for file in $FILE_PATH/*.dat
do
	echo "Processing $file ..."
	# take action on each file. f store current file name
	./UFTFTP_SecondScript.sh $file $USERNAME $PASSWORD $SERVER $FILE_PATH $REMOTE_PATH
	echo "Seconds until next upload: $WAIT_TIME"
	#for (( x=0; x<$WAIT_TIME; x++ ))
	x=0
	while [$x -lt $WAIT_TIME];
	do
		echo "Sleeping for $x"
		sleep 1
		x='expr $x + 1'
	done
done

Now the problem is connecting to the ftp.

Code:
+ ftp -n -i
Not connected.
Not connected.
Not connected.
+ echo Seconds until next upload: 300
Seconds until next upload: 300
+ x=0
+ [0 -lt 300]
./UploadFileToFtp.sh: 1: [0: not found
