Hi @embedit , in order to use the {{COL.NAME}} replacement you would need to create a separate dataset containing the formula column that formats the date as needed. You would then need to add a single row to this new dataset.
Next, Edit the original Dataset and navigate to the Advanced tab. Click on the drop-down for ‘Depends on Dataset’ and select the new dataset containing the formula, then click on Save.
Now you can add {{COL.NAME}} into the URL where NAME is the name of the formula column in the dependent dataset.
Kind Regards,
Frazer
