Case Insensitive search

Hey , i am trying to do a search for the certain books , and im trying to make it case insensitive. what i have come up with so far is this :

Code:
Database.txt
RETARDED MONKEY:RACHEAL ABRAHAML:30:30:20
GOLD:FATIN:23.20:12:3
STUPID:JERLYN:20:40:3



Code:
echo -n "Title: "
read Title
echo -n "Author:"
read Author
echo ""
 
valuecheck=`grep -i "$Title" Database.txt | grep -i "$Author"  | awk -F":" '{ print $1}'`
echo $valuecheck
if [ $Title = $valuecheck ] ; then

echo "HOHOHO"
else 
echo "too bad"

fi

the issue which i am having is that, when it does the search for the correct row to be inputted into valuecheck , it will input the value as written in the database, which is in Uppercase.

For this case, if i type in stupid for $Title and jerlyn for $Author, it searches the correct row, but the awk will print "STUPID" into the variable as that is what is written in the database.

so how can i make my if statement case insensitive? currently it reads like this
i
Code:
f [ $Title = $valuecheck ] ; then

which means

if [stupid = STUPID ] ; then

how can i make it case insensitive to allow it to display "HOHOHO"

NAME
gnome-search-tool - the GNOME Search Tool SYNOPSIS
gnome-search-tool [options] or select Search for Files... from a Main Menu or from the Places menu in a Menu Bar DESCRIPTION
GNOME Search Tool is a utility for finding files on your system. To perform a basic search, you can type a filename or a partial filename, with or without wildcards. To refine your search, you can apply additional search options. GNOME Search Tool uses the find, grep, and locate UNIX commands. The case sensitivity of the search depends on your operating system. For example, on Linux, the find, grep, and locate commands support the -i option, so all searches are case-insensitive. For full documentation see the GNOME Search Tool online help. OPTIONS
