"CompteDeNoCours" }. Select this and then press Ctrl + F9 to enclose it in
a second pair of field delimiters, the between the { { enter the equal sign
and between the } } enter *700, so that you have
{ = { MERGEFIELD "CompteDeNoCours" }* 700 }
Press Alt+F9 to toggle off the display of the field codes.
