RE:TRUCLIENT value capture & substitution

Hi Experts,

We have been working on a application using HP LoadRunner TruClient protocol, were we come across an issue with substituting a captured value.

It comes like this.

1. We are capturing a value(Transaction number, which differs on each iteration) from a pop-up window after saving the data.

2. The captured value is being saved to a variable(TranNo) and need to be used around   3-4 steps later, in a search text box.

How do we call the variable, so that it can be used in the text box arguement.

Any suggestions welcome.

Tried using LR.getParam method and all, but it is typing the variable name itself, instead of typing the captured value.

Thanks in Advance
