I want to track when users complete and drop out of completing a multi-page form. I'm capturing the "step" number as the user accesses each step/page in the form via G Tag Manager. I can see the step values in GA4 Debug (i.e., 1, 2, 3 and 4) so the steps are being collected. I've also created custom dimensions for the column/row headers and a custom metric for the "step_value" to use in reports. Additionally, the custom metric is set to "Standard".
However, I'm unable to create a meaningful report with the data.
I'd like to see a report similar to below, however, under each step/page the values are always "0" instead of values 1-4. Is this possible in GA4 or do I need a different tool?
