Question Activity Not Recording

I am having a problem with my VBActivity system im sure its some thing small but I followed the documentation with all the settings I made some categories and achievements and its showing in the vbactivity actions but when posting it does not show activity nothing happens no achievements are given, so i'm figuring there is some thing i'm missing just don't know what it is

I got this working but there is one thing

How can I make it so members get credit for there activity that they made in the past to bring it up to date?

Under DBTech - vBActivity admincp menu group, click Maintenance then click Recalculate Points. Once you've done so, and it's back on the main maintenance screen, click Recalculate Achievements
