LoadRunner correlation phenomen?

Question

I am correlating values in the response header (scope=headers) and printing the value twice in the script, but it shows different values in different places in the script: Here is the log:

Isn't that strange?

it appears that the 'corrID1 above changes its value when the script continous to execute and reffering the parameter further below actually results in it being another value, but it Works in that Scope. Strange... — Magnus Jensen, Mar 11 '13 at 19:57

Going by your output log it looks like the parameter corrID1 already exists with a value of "3" before the first POST you have mentioned in your code and then you call it again for the subsequent call which populates the same parameter with a new value. Are you sure you're not calling web_reg_save_param_ex for corrID1 earlier in the script?
