Hi,

Could someone suggest why I am having a problem (actually not me but the customer) in the following segment of code:

The container with the text box has a property control_source. This property has a value V_WORK.EMPLOYEE

The code then checks is the value of the field EMPLOYEE in the cursor V_WORK has been change. Here is the code:

		cControlSource = ALLTRIM( this.control_source )
		IF EVALUATE( cControlSource ) == OLDVAL( cControlSource )		
			RETURN .T.
		ENDIF 

The problem occurs on the line above, EVALUATE( cControlSource ) == OLDVAL( cControlSource ), and it does
ALIAS IS NOT FOUND. I verified that the entry in .control_source exists as described above.

TIA.

UPDATE. the following code checks that the alias V_WORK exist and is open. This code, below, is before the code above (just in case someone wonders if the alias is indeed exists and open

IF !EMPTY( this.control_source )
	cAlias = SUBSTR( ALLTRIM(this.control_source), 1, AT('.',ALLTRIM(this.control_source)) - 1)
	IF SELECT( cAlias ) > 0
		cControlSource = ALLTRIM( this.control_source )
		IF EVALUATE( cControlSource ) == OLDVAL( cControlSource )		
			RETURN .T.
		ENDIF 
      ENDIF
ENDIF
