Text file to a variable

I have a variable which is not being populated with the contents of a text file, and I'm wondering if anyone happens to know how to do this for a sh type script?

#!/bin/sh
set alertperson = cat /export/home/bdodym/alert.person
if [ -f /export/home/bdodym/critabend.tag ]
then
cat /export/home/bdodym/callout6.msg | rmail $alertperson
rm /export/home/bdodym/critabend.tag
fi

Basically, the alertperson variable is not reading the contents of /alert.person (which is a text file simply containing 1 email address).

I appreciate any assistance....

I wish it were that easy Ikon!

Amended script:
#!/bin/sh

alertperson = cat /export/home/bdodym/alert.person
echo $alertperson
if [ -f /export/home/bdodym/critabend.tag ]
then
cat /export/home/bdodym/callout6.msg | rmail $alertperson
rm /export/home/bdodym/critabend.tag
fi

Response:
6check2.sh: alertperson: not found

Recipient names must be specified

Beware of character spacing - very important in the world of unix.

Code:
alertperson=$(cat /export/home/bdodym/alert.person)
echo $alertperson

...thankyou, but still its proving tricky this!!

Amended script:
#!/bin/sh

alertperson=$(cat /export/home/bdodym/alert.person)
echo $alertperson
if [ -f /export/home/bdodym/critabend.tag ]
then
cat /export/home/bdodym/callout6.msg | rmail $alertperson
rm /export/home/bdodym/critabend.tag
fi

Response:
6check2.sh: syntax error at line 3: `alertperson=$' unexpected

Question
What is in your file alert.person?

Code:
> cat ~/tmp/alert/alert.person
Mickey Mouse
> alertperson=$(cat ~/tmp/alert/alert.person)
> echo $alertperson
Mickey Mouse
> echo "$alertperson"
Mickey Mouse

worked for me... It put the contents of alert.person in the variable $alertperson.

Code:
# echo "Jim Smith" > alert.person
# alertperson=`cat alert.person`; echo $alertperson
Jim Smith
