Hi I am trying to alter a sugested save as code which currently looks like this:Sub buttonSave_Click()'Prompt to save fileOn Error GoTo Error_Handler' Keyboard Shortcut: Ctrl+Shift+GDim strFilePath As String'Prompt for a WO if none inputstrWO = Sheet1.txtWO.TextIf IsNull(strWO) Or strWO = "" Then MsgBox ("Please enter a work order number so you can save the jobsheet.") Sheet1.txtWO.SetFocusElse strFileNameSuggestion = "JS-" & Sheet1.txtWO.Text & "-" & Sheet1.txtAddress.Text 'expression.GetSaveAsFilename(InitialFilename, FileFilter, FilterIndex, Title, ButtonText) strFile = Application.GetSaveAsFilename _ (strFileNameSuggestion, Title:="File Save as", _ FileFilter:="Excel Files *.xls (*.xls),") If strFile = False Then MsgBox "File NOT saved", vbExclamation Else ActiveWorkbook.SaveAs Filename:=strFile End IfEnd IfGoTo Error_EndError_Handler: Error_End:End SubThis was not written by me and gives a nice message box if the work order box is left blank prompting for it to be completed.What I would like to do is alter this to stop staff entering extended work orders - we have a long version and a short version Long e.g. = 120000654321Short (required) e.g 654321 (just the last 6 digits from the long work order are required)I would like a message box warning to pop up if anyone tries to save the sheet with the long work order (as opposed to the short) saying "Please enter a work order number leaving out 120000 so you can save the jobsheet.")Any help is much appreciated.
