The numerical values in the LOGO! are integer values, the value range is from 32,768 to 32,767), e.g. AM and VW. The exceptions are the counters, here the number range goes from 0 to 999,999 and these are double integers. If you want to represent negative numbers in the web server, you can only use integer values and then the block format signed. If you disagree, show us an example. Or upload your LOGO! Program and your LWE project in zipped form and describe exactly which blocks you mean.

I wrote you what you should parameterize the value. I took a screenshot of the parameters. Then I asked you for an example of what you don't do. Then I also asked you to upload your LOGO! Program and the LWE project, which you don't do. ixo65 If you disagree, show us an example. Or upload your LOGO! Program and your LWE project in zipped form and describe exactly which blocks you mean. Do you see the difference whether you choose unsigned or signed?
