A common reason merge fields do not merge at all or do not merge as expected in PowerPoint templates is because there are multiple merge fields in the same text box.

Cause

A common reason merge fields do not merge at all or do not merge as expected in PowerPoint templates is because there are multiple merge fields in the same text box.

What to Do

Put all merge fields into their own text boxes. See Add a Merge Field to a PowerPoint Template for more information.

The GroupRepeat function does merge as expected.
