That's odd. I generally copy and paste before saving. Try this. Fist make sure that you have clicked on options in UF and updated all the public formulas. Then try to right click on the flame and click then on 'save as upr'. Open UF and either right click and paste, or use the paste icon in the toolbar. UF will show you a window that says it is looking for a possible match, ... be patient a moment and allow it to find the sdc+enr-flame-a in uf. Then click on 'use the formula selected above' and allow the flame to paste in. Then if it shows up right, click on save, to save the file within UF, or click on the icon for 'save parameters'. That's the way I do it. I'm sure Rick has explain further about how he does it. Good luck! Once you finally get it , you'll see it's a piece of cake. :)
