Written Communication auto SUM for invoice

[berd]

Hello,

This Written Communication is a very nice plugin, i am trying to make simpel invoices out of it instead of using the complex Mitgliedsbeitrag plugin. I have this almost running but there is one thing which is not working maybe is there someone who can help me for this very generic solution.

My custom profile fields which will be shown in the template after the fields have be filled in the profile.

CONTRIBUTION € 200
RENTAL EQUIPMENT € 100
RENTAL LOCKER € 100
BORG € 100
DISCOUNT € 100

What i want is to make a total amount of the sum so that would be € 600,--
I have used the =SUM(ABOVE) value from Word in the table.

Code: Alles auswählen

${UserContribution}
${UserRental_locker}
${UserRental_equipment}
${UserBorg}
${UserDiscount}
Total €    0,00

In the total Row i have used the word formula =SUM(ABOVE) which give me a total of € 0,00 when the file opens in Word. (when i the select the formula by hand he calculates the total SUM)
Is there some trick maybe from the plugin to get a total of the number? This way you can also use this plugin for a simple invoive system!

Thanks for this great plugin!
