Increment logic in script

Hi All,

In the Script i am using the SAPSCRIPT-COUNTER_1.

I have assigned the value '0' to it.

But after that i want to increment it.i am using the command which is in bold.

But the value is not incremented.

/: DEFINE &COUNTER_1& = '0'

<b>&COUNTER_1(+)&</b>

Please Suggest me....

Regards,

Swathi
