I searched but didn’t find this already reported.

When setting a tag’s OPC Item Path in a UDT to use a number formatted parameter like:

```auto
ns=2;s=[default]PARK/WEC{PARAM_TURBINEID|#00}/_diagnostics_/Is Connected

```

the parameter doesn’t get zero padded:

```auto
ns=2;s=[default]PARK/WEC1/_diagnostics_/Is Connected

```

Thanks.

Hi @malone46844,

I’ve been able to reproduce this bug in 8.0.3. Seems like number formatting doesn’t work for constant parameter expressions such as your case. As a workaround, you can try doing adding a trivial operation to the constant expression, such as PARAM\_TURBINE\_ID + 0. I’ve attached the ticket number to this post to keep track of its progress.

Thanks,  
Alen

{Param **+ 0** |00} worked like a charm. Thank you much for the workaround.

Hey guys, this is still a bug and +0 didn't work for me. Any update on this? Cheers.
