Error Nested if with multiple conditions

Deal Experts

I am working on a script to find a date which is 7 days older and follwoing is my approach
Code:
#!/bin/sh
Yr=`date +"%Y"`
Mn=`date +"%m"`
Md=28
Da=`date +"%d"`
echo $Yr
echo $Mn
echo $Da
var1=$Yr$Mn$Da
echo "before" $var1
if expr $Da > 7
then Da=`expr $Da - 7`
var1=$Yr$Mn$Da
echo $var1
fi
if expr $Da <= 7
then 
if $`expr $Mn -1` < 1
then 
Mn=12
Yr=`expr $Yr - 1`
else 
Mn=`expr $Mn - 1`
fi
fi

it is giving error on line 16th saying
A file or directory in the path name does not exist.
Code:
Date.sh[16]: =: 0403-016 Cannot find or open the file.

I am not trying to open or access any file but still it is throwing the error

Please help
