Hi Kelly,
To control number & currency formatting in Word, add a numeric picture switch to the mergefield. To do this:
.. select the field;
.. press Shift-F9 to reveal the field coding. It should look something like {MERGEFIELD MyData};
.. edit the field so that you get {MERGEFIELD MyData \# $,0.00} (or whatever other numeric format you prefer - see below);
.. position the cursor anywhere in this field and press F9 to update it;
.. run your mailmerge.
Note: The '\# $,0.00' in the field is referred to as a numeric picture switch. Other possibilities include:
.. \# 0 for rounded whole numbers
.. \# ,0 for rounded whole numbers with a thousands separator
.. \# ,0.00 for numbers accurate to two decimal places, with a thousands separator
.. \# $,0 for rounded whole dollars with a thousands separator
.. \# "$,0.00;($,0.00);'-'" for currency, with brackets around negative numbers and a hyphen for 0 values
The precision of the displayed value is controlled by the '0.00'. You can use anything from '0' to '0.000000000000000'.
If you use a final ';' in the formatting switch with nothing following, (eg \# "$,0.00;($,0.00);") zero values will be suppressed.
Note that this suppresses 0s resulting from empty fields and from fields containing 0s.
