Concatenation allows you to join fields or values together like you would using an Excel function. For example, you could join your brands and titles or you could append colors to the end of your titles or units of measure to shipping dimensions.

1. Brand + Title = "TREK Basketball Shoes"
2. Title + " - " + Color = "Boys shirt - Blue"
3. Shipping length + " in" = "3.5 in"

How to concatenate values in a rule:

1. In the feed, select 'Rules' from the left-side menu
2. Click the blue + button
3. Name your rule, and optionally set a rule description
4. Under SET, select the feed field you want to change with this rule
5. Under TO, enter the desired value for your selected field by either typing it in, or choosing from either your imported Product data ([P] fields) or Feed data ([F] fields) from the drop-down menu
6. To concatenate fields, you will add another field or value in the next available box
7. Use the space key to give a space character between fields/values (see image above)
8. Enter the conditions for this rule -- To add additional conditions, click the + Condition icon
9. Click the "Save" button

To save this new custom rule as a Global Rule, click the global rule drop-down option and select Save as new global rule.
