I don't think is going to suit my needs
I have a feeling that I am barking up the wrong tree - excuse the pun based on your old Avatar
My problem is that I somehow need a cell to recognize its contents and then display the appropriate help text.
For example ANT001 thru ANT012 inclusive are all antennae. The accompanying text would be
[Antennae location] | [Mounting height]
ANTX01 thru ANTX01 is an external antennae and the text would be
[Antennae location] | [Mounting height] | [Mount type] | [length]
To a trained user the difference would be second nature but to someone less experienced it's a nightmare. They have to keep looking it up and this takes time - and money!
Is it possible for the cell contents to be recognized and then display the appropriate help text?
