A few weeks ago ago I was having trouble with a write cell / concatenate problem. The problem was solved HERE, however my formula has since broken.
I did notice that the second half of the formula is green, am I over looking something simple here?
Write Cell: The write operation failed, because one of the following reasons:
► The data you want to write “=CONCATENATE(“E”&TEXT(G2,“mmddyy”)&”-‘’&TEXT(H2,“mmddyy’')&” “&Q2&” “&“P”&F2&” “&P2)” has a wrong format;
► Excel is busy or you are currently editing a cell;
► If your data is a formula, make sure you use comma as parameters separator;
► During the write operation make sure no dialog windows are opened.
Seems that you are having some problems with quotations marks.
You can try put this formula inside a txt file, asset or a storage bucket, writing it like you are writing on the excel and then reading the file/asset/storage bucket file and puting it inside a String variable and writing this new StringVariable inside the cell.
