I have a mergefield with numbers using the period character as a thousands
separator (eg. the value "one thousand" is stored as "1.000").

Trying to make an IF statement, I get problems with Word understanding the
value one thousand (1.000) as the number 1 (with 3 decimals):

I.e.
{ IF { MERGEFIELD L01b } 400 €�Hi€� €�€� }
shows nothing if the L01b value is above one thousand.

Any suggestions as to how I can fix this?
