/usr/local/bin/expr function not working

Legends,

I am not able to set "expr" function in ksh script.
Below is the sample code i used, and output is as "Syntax error"
Please help me to come out of it.


Quote:
DATE1="`date -u +%Y`"
DATE2="`date -u +%m%d`"
CurrentDate="$DATE1$DATE2"
print "CurrentDate = $CurrentDate"
cutoffdate=`/usr/local/bin/expr $CurrentDate - 3`
print "cutoffdate = $cutoffdate"
cat /tmp/loadDSdata.tmpl|while read BASENAME
do
Len=`/usr/local/bin/expr length $BASENAME`
Len=`/usr/local/bin/expr $Len + 2`
Len2=`/usr/local/bin/expr $Len + 7`

print "Len = $Len"
print "Len2 = $Len2"

OUTPUT

Quote:
CurrentDate = 20120315
cutoffdate = 20120312
expr: syntax error
expr: syntax error
expr: syntax error
Len =
