export the User Defined Variables

Hmmm, I suppose if I were to try this I'd take the following approach.

Create a topic you will use to transfer the variables. Insert each variable on separate lines. Follow each of the variables with the actual text or whatever the variable contains on the line before or the following line.

Save the topic and import it to the destination project. Assuming the variables don't exist, you should see something like this:

This is where the variable text will come in. Select and copy the variable text or image or whatever the variable should contain. Then double-click that ERROR bit and you should see this:

Here is where you will paste what you copied. However, a variable may also contain an image. So if it was an image, just type something like XX into the field and click OK. Then paste the image into the Variable pod.

Rinse and repeat as needed until all variables have been created.
