How do I Make Text input become a varible?

Hi guys,

I have been searching for an answer but it seems to be the opposite of what i want,

Asking for text to show varibles, i need it the other way around :)

Hopefully these images show up, so it's easier to explain

For this one i want to write the text input of the order number in the box where highlighted.

And this is why i need varibles, when the dispatched name is clicked, I would like it to show the said info that was just input into the fields.

Is this even a varible things, or do i need to learn arrays or strings?

Any help is much appreciated :)

Then last part for the adding an order part, Which Dispatch lane will it be 1-9

Then it will ask for the number of pallets for the order, this will need to be manually input also

Use an array to store the data. Columns for name, volume and lane.
