permit input but prohibit delete

[f_b2050]

Hi All,

I want to make a template where it should be possible to add data but it should be prohibited to delete data (not by deleting lines, but also not by deleting data from cells.)
I tried to fix it with a VBA code i found online but that doesn't work.
Who has the solution?

Thanks in advance!

PS i can't see whether i can post an attachment.
