Pull Same Cell from Multiple Sheets into one Row

Hi everyone,
New here, but I did search the threads to see if my answer was on here somewhere, and I couldn't find something that worked for me. I've seen a lot of threads with the Indirect Function which I think I understand, but I keep getting the #REF! every time I've tried.

I need to pull values from the same cell on different sheets, and create a list on a Summary Sheet.

For example, I would like to pull cell F20 on all of my previous sheets (let's say Sheet 1 through Sheet 10) into Column D of "Summary Sheet". I'm looking for a formula I just drag from D3 to D13 to populate it.

Extra Question - Is there also a way for me to add sheets, and the summary sheet will also pick up on the added sheet, and insert the value into the Summary Sheet?

Many thanks in advance.

Thanks Special-K. But I'm not trying to enter use a formula with that Data. It seems like the 3d reference would only be used to do something with the data in the same cells (sum, avg, etc).

I just want it to populate into different in a column. I could just do a =Sheet1!F20 into D3 of my Summary Sheet , Sheet2!F20 in D4, =Sheet3!F20 in D5 and so on. So that's why I'm wondering if there's a formula that can be dragged down since I'll be doing this for hundreds of data points and multiple lists.

Awesome! Thanks JeteMc. This worked great. My follow up questions:

I'm trying to understand formulas better, and I understand that the "Sheet" means that any sheet that has the name sheet in it, it will pull from (I think), but what's the purpose of putting the &ROW(A1), which drags down?

My second question is it possible to have a formula similar to this while changing the Sheet Names? For example, I will be using this spreadsheet for apartment units, so how would the formula change if I named the Sheets, 101A, 101B, 103C, 103D, etc?

Thanks again - this is great for what I need.

This is great! Thanks so much!
