The user is unable to proceed with a mail merge because the 'Continue to Send' button in the Doug Robbins Merge Tool add-in is grayed out or disabled.

How to Fix the Disabled Continue Button in the Doug Robbins Merge Tool

Product: Doug Robbins Merge Tools Add-in for Microsoft Word
Device & OS: not provided
Scenario: The user is attempting to execute a mail merge to generate separate Word or PDF documents and send them via email using the third-party add-in.
Observed behavior: The 'Continue to Send' button remains unresponsive and disabled after configuring the initial tool settings, preventing the merge process from completing.

Before you start

Ensure that your data source (like an Excel spreadsheet) is properly connected to your Word document and that the document contains at least one valid merge field.

Solution 1Recommended

Select the Required Filename Field in the Merge Dialog

The Continue button remains disabled when a mandatory selection is missing from the merge dialog, most commonly the field designating the filename for exported Word or PDF documents.

The Doug Robbins Merge Tool requires specific data to function properly, particularly when generating individual files. If you are using the 'Merge to Email as Word or PDF' destination, the tool needs to know what to name the generated attachments. Failing to select a data field for this filename will keep the Continue button grayed out.

Open the Merge Tool Dialog

Launch the Doug Robbins Merge Tool from the Word ribbon and proceed to the main configuration dialog box.

Locate the Filename Configuration

Find the section labeled 'Merge to Email as Word or PDF destination' or similar, which handles document generation.

Select the Filename Field

Click the dropdown menu for the filename and select the specific field from your data source that contains the desired file names (e.g., 'CompanyName' or 'LastName').

Verify Button Status

Check the bottom of the dialog box. Once all mandatory fields including the filename are populated, the 'Continue to Send' button will automatically become enabled.

Select the Required Filename Field in the Merge Dialog

Double-Check All Dropdowns: If the button is still disabled, review every other section in the dialog box to ensure no other dropdown menus or required checkboxes have been left blank.

Resolve Document Formatting Inconsistencies

Frequently Asked Questions

Why is the Doug Robbins Merge Tool Continue button grayed out?

The Continue button remains disabled when you have not completed all required selections in the add-in's dialog box. This most commonly occurs when exporting to Word or PDF, and the user forgets to select the data field that dictates the filename of the generated documents.

Where can I find the filename field option in the merge dialog?

Look for the dropdown menu under the 'Merge to Email as Word or PDF' destination section. It specifically asks you to select the field containing the data that will be used as the filename for the created attachments.

Can I perform a mail merge without third-party add-ins?

Yes. Modern office suites like WPS Office and Microsoft Word feature built-in Mail Merge tools found under the References or Mailings tab. These native tools allow you to connect spreadsheets, insert merge fields, and generate bulk documents directly.
