Your pattern does not match the space before the numbers, and it has  
mismatched capturing and literal parentheses.

You want:
^ *Hp: *(\d+)\((\d+)\) +Gp: *(\d+)\((\d+)\) +Xp: *(\d+) +Quest Xp: *(\d 
+) +Socp: *(\d+)\((\d+)\) *$

Note that there is a "\(" "\)" for each "(" ")" in the original, and  
there is a " *" or " +" for every space in the original.

Now, count the capturing parentheses "(" ")" to determine their numbers:
   1 Hp
   2 Max Hp (I assume)
   3 Gp
   4 Max Gp
   5 Xp
   6 Quest Xp
   7 Socp
   8 Max Socp

so for this trigger you will want to use arg[1] and arg[3] in the  
script to get the Hp and Gp fields.

If you don't care about any of the fields, you can skip the capturing  
parentheses around them, too:

^ *Hp: *(\d+)\(\d+\) +Gp: *(\d+)\(\d+\) +Xp: *\d+ +Quest Xp: *\d+  
+Socp: *\d+\(\d+\) *$

This pattern will match *only* Hp and Gp and put them in arg[1] and  
arg[2]. However, I myself would choose the first pattern I gave which  
captures *every* field, so that if you want to add additional actions  
to do based on your hp bar you can add to the script without adding

You have a missing space in the second @@if, and no @@end for the  
first one. (These mistakes should be mentioned in the little script  
error popup.)
