Hi NLtL,
I've made some screenshots to clarify what I am trying to obtain:
In "Image sheet1" we have a simple table with particle sizes in one column and the column next to that needs to be filled out by the QC lab with the amount that was found in their analysis. In this case they just measured lot D
In "Image sheet2" we find that same setup, but it is an overview of all the data obtained for the lots they analysed historically.
As you can see lot D is still open on this sheet and I would like excel to add another column on this sheet with the data for lot D, once QC filled it out on sheet 1. And then again for lot E, F, etc.
So sheet 1 is the standard entry sheet and sheet 2 needs to continuously add columns once data is entered in sheet 1.
And on top of that, the average and STDEV calculations need to update along with that.
This is all very simple if you manually insert the new column into sheet 2, but I need the excel file to be validated, which means sheet 2 will be protected and cannot be manually adjusted.
Hope this makes a bit more sense
Johan
