royalmarine Posted May 19, 2013 Share Posted May 19, 2013 Hey guys, can someone have a quick look and see if they can spot why this statement is not working for me? The function works, but the if statement to ensure the value is not below 0 does not. Case $Button4 If GuiCtrlRead($input5) = "" Then MsgBox(0, "Error", "Input box empty") Else If GUICtrlRead($Quantity - (GUICtrlRead($Input5)) > 0) Then MsgBox(0, "Error", "You can't have negative stock!") Else $RemoveStock = ($Quantity - GUICtrlRead($Input5)) _ExcelWriteCell($datasheet, $RemoveStock, $iIndex, 3) $input = GUICtrlRead($Input1) $iIndex = _ArraySearch($aArray, $input, "", "", "", "", 0, $sColumn) $Quantity = _ExcelReadCell($datasheet, $iIndex, 3) GUICtrlSetData($Stock_Quantity, $Quantity) GUICtrlSetData($Input5, "") EndIf EndIf Link to comment Share on other sites More sharing options...
water Posted May 19, 2013 Share Posted May 19, 2013 Values returned by GUICtrlRead are strings.
