Hi, me again.  
I want to do some awesome automation in workflow. However, it seems that the` set Variable` action in `Workflow` only supports `string` (even cannot plus a number). Is there any reason that we can’t use the` Expression Editor` in `Workflow`?

@john55ww We know that the expression editor for forms is much more powerful than the workflow editor. We are trying to bring it into the workflow. For now, there are some workarounds to consider:

- Put calculation in form
- Change or involve data list into the workflow, using Calculated Column do the task
- Put the calculation in some 3rd party service, e.g. Azure Cloud API
- Use Yeeflow connector in Power Automate with data list to bring more possibilities
