Possible issue with Iframe names?

[galatai]

Have created an Iframe with the address https://ciu.xxxxx.co.uk/DBcreate/CIU-Events-100.php which works well, however, when I go to edit this for another page to go into the frame ... https://ciu.xxxxx.co.uk/DBcreate/CIU-Events-200.php and just change the 100 to 200 then the CIU-Events part turns into CIU-events and obvoiusly the page will not load due to the difference in name. The CORRECT address is shown on the WYSIWYG but selecting the frame it becomes incorrect. The only way round this is to rewrite the whole of the https address again and re-publishing.
Could you have a look at this please? Thanks
Keep up the good work!

Is your question referring to the built-in inline frame object or are you using the "iframe resizer extension?

Am using the frame inside a layout grid and using another auto resize program to automatically change the size of the frame. This code is after the frame. The re sizing code does not come into the equation as this is just as the editor sits there and then I change the address without publishing.
Had a thought.... is this due to spell check on the address due to using a hyphen in the address as it is not normal to have a capital letter after a hyphen?
Thanks
