How to store servers load value in variable

I'm going to store last five minutes server load into a variable in a shell script. I use the following command which works perfectly:

    uptime | awk -F 'load average:' '{print $2}' | awk -F', ' '{print $2}'

OUTPUT : 0.24

But when I create a shell script file it print whole uptime output.

Here is my shell script :

#!/bin/sh
uptime = $(uptime | awk -F "load average: " '{print $2}' | awk -F"," '{print $2}')
echo $uptime

OUTPUT : 19:39:22 up 52 min, 2 users, load average: 0.03, 0.12, 0.20

What is wrong in my shell script ?

Remove the extra spaces around the =, like so:

#!/bin/sh
uptime=$(uptime | awk -F "load average: " '{print $2}' | awk -F"," '{print $2}')
echo $uptime

This worked fine for me.
