MEANIN INFORMATION NEEDED DIALOG

The 'Meaning Information Needed' dialog is used when the user selects 'Weighted Mean' from the Analysis Dialog. It is used to collect extra information needed for this type of analysis. It allows single or multiple soil layers to be selected. It only displays soil layers that are present in the state being analyzed, however all layers may not be present in every MUID or component of a MUID. Text must be entered into the 'Output Item Name in Table' to allow the NEXT button to be depressed. The 'Percent Component Used:' will not appear if the user does not select 'Include Component Percentage Item in Analysis' in the 'Analysis Options' dialog.

The 'Component Percentage Item:' text will only be present if the user has selected the item in the Analysis Options dialog. The user can press NEXT to start the analysis or BACK to correct information in either the Analysis dialog or the Meaning Information dialog.
