2. Click the Options tab.
3. If the Active check box is cleared, the Block is not active.
If the Active check box is selected, the Block is active.
To set up a block as active:
1. Right-click the Block, point to Set, and then click Is Active.
2. In the dialog, select TRUE to specify that the Block is active, or select FALSE to specify that the Block is not active.
3. Click OK.
