Click Button - Export values on click or similar (help wanted)

Hi im writing my master thesis, and im almost done, as a last step i want my values to be exported to excel, and i know how to do this BUT.

My problem is that i want to repeat the calculation with different parametars, and after that upon the users will, the values will be exported.

In my case, i have done a automatic export of the values upon every recalculation and i want a button of some type that does this when clicked

The task: One button click to export all the matrixes.

Ofc the script will be later integrated into my orginal script and Matrix A to E will be different and present different load-cases and stages.

Also if you cant help me, you might want to take a look into the strings I have created that first calculates how many rows in excel that have been used and print the data after that row, so you can collect samples for different input-data, into same file without having to change the write function manually.

Im also aware that i could do a for loop to make the script shorter, i will do later. Im asking about the button
I have checked scripts recommended for using buttons to export data to txt. but they didnt work in mathcad 15.

If you can, i want the button to be double clicked to activate it.
