Mail Merge - Conditional formatting of cell background color

[wrd_xcl]

Hi All,

I followed the instructions above and use this as a reference:

{IF{MERGEFIELD Condition}= "HIGH" "→→↵
→→↵
→→" \* Charformat}{IF{MERGEFIELD Condition}= "MID" "→→↵
→→↵
→→" \* Charformat}{IF{MERGEFIELD Condition}= "LOW" "→→↵
→→↵
→→" \* Charformat}

I've set the margins (all sides) to 0, the tab is set to cell width, it's right-aligned, I use TAB (ctrl-TAB) because it's inside the cell, and for RETURN (shift-enter).but all I got is "Unknown Switch Argument". Please help

Here's a screenshot of current work. I highlighted them to show the tabs.
