Change your if statement to:
if grep "$Title" Hello1 | grep -q"$Price" ; then
You were missing your grep command after the pipe, so the shell was trying to find a command called "-q20" and so it gave the error.
Also you should remove the first "-q" so that the output passes through the pipe for the next grep.
This will help the first problem but you will run into issues if you search for a $Price that equals the Quantity value. You will have to use awk or cut to check the position of the value to make sure you found the correct entry.

ZGREP(1) General Commands Manual ZGREP(1)
NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and
fed to grep.
If zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses
it as the grep program to be invoked. For example:
for sh: GREP=fgrep zgrep string files
for csh: (setenv GREP fgrep; zgrep string files)
