Using coefficients and hazard ratios of a validated risk score calculator to determine the risk profile of a population using SPSS

This post has NOT been accepted by the mailing list yet.
I want to analyse the cardiovascular risk profile of a population using Framingham risk score.I already have the values of body mass index, age, sex, hypertension and etc (that are used in this calculator) for each observation of my study.I also know the coefficients and hazard ratios that I want to use and they were previously determined by Framingham study (which were estimated by Cox regression analysis).But which statistical analysis should I perform on SPSS to know the cardiovascular risk of my population? I can´t perform a cox regression based only on my data because I didn´t evaluate a population over years.For example, I can´t tell how much will someone´s age impact on the risk for a cardiovascular disease during 10 years.I simply collected the data in a cross-sectional design.Thank you very much!

Look up COMPUTE command or what are you not telling us?

DO IF will be handy too.

The RANGE() function might be useful too.  From the Universals section of the FM:

RANGE(test,lo,hi[,lo,hi,..]). Logical. Returns 1 or true if test is within any of the inclusive range(s) defined by the pairs lo, hi. Arguments must be all numeric or all strings of the same length, and
each of the lo, hi pairs must be ordered with lo <= hi. Note: For string values, results can vary by locale even for the same set of characters, since the national collating sequence is used. Language order, not ASCII order, determines where certain characters fall in the sequence.
