Merge field won't display if number is 0.00

Question

When the value 0.00 is brought into the word document via merge field, nothing displays.  If the value is greater than 0.00, it displays that value.  Is there way to display the 0.00?

Answer 1

To control number & currency formatting in Word, add a numeric picture switch to the mergefield. To
do this:
• select the field (e.g. «MyData»);
• 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.
Note1: 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.
If the above doesn't resolve your issue, it may be that the expected zeros are actually empty fields. In that case, you should be able to get the desired output by embedding the MERGEFIELD in a formula field, thus:
• select the field (e.g. «MyData»);
• press Ctrl-F9 to embed the field in another field, thus { «MyData» };
• edit the field code so you get {=«MyData» \# $,0.00} (or whatever other numeric format you prefer);
• position the cursor anywhere in this field and press F9 to update it;
• run your mailmerge.
