Need to change font color along with static data in an if else statement

I am trying to change the font color in the bip form but I am unsuccessful.

This is my coding today without the attribute that puts the amount at 0.00 if the extended amount = 0 or the field does not exist.

<?xdofx:if Extended_Price_ID27 !='' then Extended_Price_ID27 else

0.00

end if?>

I have tried the following with no success:

• <?xdofx:if Extended_Price_ID27 !='' then Extended_Price_ID27 else <?attribute@incontext:color;'red'?>0.00
  end if?>
• <?xdofx:if Extended_Price_ID27 !='' then Extended_Price_ID27 else 0.00 <?attribute@incontext:color;'red'?>
  end if?> (displays end if as comment)
• <?xdofx:if Extended_Price_ID27 !='' then Extended_Price_ID27 else 0.00 attribute@incontext:color;'red'
