The plot thickens

I had an idea to debug this , im breaking it right down to basics

When I execute this from a script in the same directory as the given .jpg file it WORKS


echo I am doing this from a script
convert ‐resize 120x120 apache.jpg apachetn.jpg

But when I put the filenames into variables

searchfile="apache.jpg"
tndir="apachetn.jpg"
echo I am a script that uses variables
echo $searchfile
echo $tndir
convert ‐resize 120x120 $searchfile $tndir

IT FAILS

convert: Unable to open file (‐resize) [No such file or directory].
convert: Unable to open file (120x120) [No such file or directory].

btw it makes no difference if the variables are quoted or not

So my logic tells me that the last two vars are getting lost completely and hence convert is taking -resize and 120x120 to be the filenames

???

very confused

NAME
bashbug - report a bug in bash SYNOPSIS
bashbug [--help] [--version] [bug-report-email-addresses] DESCRIPTION
bashbug is a utility for reporting bugs in Bash to the maintainers. bashbug will start up your preferred editor with a preformatted bug report template for you to fill in. Save the file and quit the editor once you have completed the missing fields. bashbug will notify you of any problems with the report and ask for confirmation before sending it. By default the bug report is mailed to both the GNU developers and the Debian Bash maintainers. The recipients can be changed by giving a comma separated list of bug-report-email-addresses. If you invoke bashbug by accident, just quit your editor. You will always be asked for confirmation before a bug report is sent. OPTIONS
--help Show a brief usage message and exit. --version Show the version of bashbug and exit. bug-report-email-addresses Comma separated list of recipients' email addresses. By default the report is mailed to both the GNU developers and the Debian Bash maintainers. ENVIRONMENT
