SYMPTOMS
When you insert a page transition on a page and then preview the page in a Web browser, the page transition is not displayed.
CAUSE
This problem occurs when another Dynamic HTML (DHTML) tag or Script tag is placed before the page transition meta tag within the source code.
NOTE: This problem can occur if you insert a page transition after you have formatted some text with a Dynamic HTML effect.
Here is an example of the HTML showing a dynamic animation tag being placed before the page transition meta tag:
<head>
<script language="JavaScript" fptype="dynamicanimation" src="animate.js">
</script>
<title>Distributed Systems</title>
<meta http-equiv="Page-Enter" content="blendTrans(Duration=3.0)">
</head>
RESOLUTION
To resolve this issue, use one of the following methods.
Method 1: Insert the Page Transition Before All Scripts and DHTML Effects
Apply the page transition before you insert scripts or DHTML effects on the page. This inserts the meta tag for the page transition in the appropriate location.
Method 2: Place the Page Transition Before All Script and DHTML Tags by Altering HTML Source Code
1. In FrontPage, click the HTML tab.
2. Select the page transition meta tag. Your tag will look similar to the following:
<meta http-equiv="Page-Enter" content="blendTrans(Duration=3.0)">
3. Use the cut and paste operation to place the meta tag before all other meta tags in the source code. Your code should look similar to the following:
<head>
<meta http-equiv="Page-Enter" content="blendTrans(Duration=3.0)">
<script language="JavaScript" fptype="dynamicanimation" src="animate.js">
</script>
<title>Distributed Systems</title>
</head>
4. On the File menu, click Save.
