Summary:
I get this error when I try to enter a tag in the Citect Graphic Builder. I checked that the tag name is correct and exist in the Variable Tags configuration. When I click on the Wizard button I get the message "List too big".

The drop down tag list does not display a complete list of tags.

 

Solution:
This error is caused when the number of variable tags in your project exceeds the "Maximum list box items" settings (Default=2000).

There are 2 solutions to this issue.

1. If you wish to use the Wizard button to insert the tag, then you can increase the "Maximum list box items" (default is 2000) to encompass the number of your variable tags. This setting can be access via the Tools/Options in the Citect Project Editor. Please restart Citect Explorer after you have update the setting so the new setting is loaded.

2. If you DO NOT wish to use the Wizard button to insert the tag, then another solution is to turn the option "Prompt on tag not exist" off. This setting can be access via the Tools/Options in the Citect Project Editor. Please restart Citect Explorer after you have update the setting so the new setting is loaded.

To display the complete list of tags in the dropdown list, the citect.ini parameter [CtEdit]MaxHelpRec can be increased. See Q3605 and Q4096 for more information regarding this paramater.

The error message "Tag not found" may also appear because the variable.dbf index file, variable.ndx, may be out of date. To recreate the variable index file, pack the project and each of the include projects. To pack a project select the project in the Citect Explorer then go to Project Editor --> File --> Pack.
