Error: Error merging document (word/document.xml): Invalid document merge data, attempted invalid math operation.

Per FormStack's Help Center:

The math operations performed contained incorrect data types. Typically, when attempting to subtract two values, at least one cannot be parsed as a numeric value.

For example:

{$number1 - $number2}
With values:
$number1 = ‘5’
$number2 = ‘test’

What action can I take?

Ensure all values that are passed into merge fields, that will be used in a mathematical operation, are numeric.

Copy calculations from an open-sourced word processor like TextEdit rather than from a program like Word to eliminate possible extra HTML properties.

Use the ‘intval’ or ‘floatval’ modifier to ensure the value is an integer or decimal (floating point) value.
Example:

{$number1|intval - $number2|intval}

The Document Template contains a division by zero as a denominator

The document contains a division operation, but the denominator is zero (0).

What action can I take?

Confirm that the data source never sends 0, empty, or null for any merge field that is used as the denominator for a division operation.

Use the |intval or |floatval modifiers to ensure the value is a numeric type.

Example: 

{if $denominator|intval > 0} 
{$numerator|intval / $denominator|intval} 
{else} 
0 
{/if}

Error: Error merging document (word/document.xml): Invalid merge data, one or more merge fields are accessing object data on a non-object.

An illegal array is offset with a string passed instead of an object in post data. An example of this could look like this:

{$Test[‘value’]} or {$Test.value}
With values:
$Test = ‘string’;

What action can I take?

Ensure all merge fields that will be used are passed in with the correct data structure. Use is_array to check that it is an array before accessing the value.

Example: 

{if is_array($MergeField)}
Populate data if array
{else}
Do something else if not array
{/if}

You can also convert the null value that is being sent over to an empty array by adding this line at the top of your document for each array:

{if !is_array($ExampleArray1)}{$ExampleArray1 = [“”]}{/if}
