Hi everyone! I've been working a code on my laptop (Excel 2010, Windows 7 Professional). Worksheet has a few macros that I made with function "Macro Recorder" (I'm not an expert, still I understand logic of my macros...). Worksheet also has some Control ActiveX Buttons that run macros or text boxes... It had been working perfect on my laptop until I send it on email to some friends. When they opened it, none of my macros work. Even a simple sheets("name").select give then an error '57121' (Application defined or object defined error). What could be happening here? How can I solve this? I hope you can help me with this..
