Hello everyone, what is the cause of this error? I am trying to show the location from the datagrid to the label

Look at the error message: it's pretty clear:
Error
Conversion from string 'Kitchen 41' to type 'Double' is invalid.
..................................................................

Input string was not in a correct format.
Location is a Double but at least one of the cells you are trying to convert contains the text "Kitchen 41" which is not a number at all.

Use the debugger to look at your DataGrid content and determine why you are trying to convert a non-numeric value. The most frequent reason is that it's the wrong column ... but we don't have access to your data so we can't tell exactly what you are trying to do.

Because this is the continuation from the other question (https://www.codeproject.com/Questions/5370000/I-want-a-solution-to-this-problem)
Perhaps you should show us per example what your DataGrid contains and what you want to add.

To continue the answer from OG :
What do you think is the sum of "Kitchen 41" and "Bathroom 12" in your opinion ?
