Hello team,  
I’m getting familiar with your nodes and I can use the browser to web scrape (yay!) and can loop through a google sheets list (yay!) yet…I can’t find help on how to loop to operate on a single a web scrape.

How do I construct a node/flow to accept a constant (a single web scrape) and also a list (from a google sheet)?

I’m trying to construct something very simple:  
a) use the single output from the chrome browser extension output (static HTML source) and  
b) loop thru an google sheet pulling things out of the web scrape.

How do I set this up?

I’m sure I’m missing something trivial.

I’m enjoying the development environment you have created!

Hey @davestein1! If you’re reporting an issue with a flow or an error in a run, please include the **run link** and make sure it’s **shareable** so we can take a look.

1. **Find your run link** on the history page. Format: `https://www.gumloop.com/pipeline?run_id={{your_run_id}}&workbook_id={{workbook_id}}`

2. **Make it shareable** by clicking **“Share”** → ‘Anyone with the link can view’ in the top-left corner of the flow screen.

3. **Provide details** about the issue—more context helps us troubleshoot faster.

You can find your run history here: [https://www.gumloop.com/history](https://www.gumloop.com/history)

Hey @davestein1 – You can use a `Duplicate` node here. The `List Size to Match` ie, the amount of times you want to duplicate the static input to match each loop iteration, would be any input from your spreadsheet (ie. Google Sheet Reader node) and the `Input` would be connected to the static HTML output.

Brilliant!  
Thank you, Wasay.  
I knew people had walked in my shoes already.  
I’ll try this during my lunch break today.
