How to place cursor on any of this 5 fields and press button 'PICK HU'

Hi ,

i have designed a screen which displays 5 output fields .

i:e

1. 500002000189 " v_exidv1

2. 577823478388 " v_exidv2

3. 578278784278 " v_exidv3

4. 572389497892 " v_exidv4

5. 578727822764 " v_exidv5

i have taken these values in an internal table i_tab1 .

Below i have a button 'PICK HU'.

when i place cursor on any of this 5 fields and press button 'PICK HU'.

I must move to next screen where i am displaying data related to that field .

Please tell me how to catch this field and take it to next screen , when i place cursor on any1 of the above fields and click button 'PICK HU'.

Points will be awarded immediately .
