GX Developer Problem

[ChrisPayne1967]

Hi all
I'm trying to edit a program I've written using GX developer 8.78. For some reason all the options in the second section of the find/replace menu are greyed out so I can't use the find/replace (ctrl H) option. Does any body know why this might be? I'm sure they've been available at some point but mostly they're grey. Thanks a lot.

Try F2 - write mode.

Ok I've had another look at the problem.
When I open a new project the options are available until I go on-line to the PLC. After that, no matter which mode I choose they are always grey.
Any ideas?

These are for 'offline' editing.

Some of the instruction will change the program in more than one place (and that is not allowed online)

Thanks goody that sorted it.
Basic mistake but I'm used to different software.
